In our how to test your MVP article, we mentioned that there’s a different category specific for software testing. Since there’s a wide range of possibilities and ideas involved in creating a product, it follows that there’s no one-size-fits-all testing that you can employ.
But don’t fret because we’ve listed out 41 types of software testing in this article to help you troubleshoot your MVP. Each type of software testing comes with a brief description so you’ll have an idea if they’re worth researching more or if they apply to your program.
Wherever you are in your product’s development cycle, any of these testing methods will be invaluable for your MVP ????. So, without further ado, here is the ultimate software testing guide for product hackers in 2021.
Once you’ve released your MVP to the market, it’s up to the end-users to decide if it is worth installing and downloading. Likewise, they decide whether it has a significant contribution to their lives or not.
Regardless of the fate of your MVP, your role as a developer is to make sure that your MVP delivers what you envisioned it to. You can validate this through software testing.
Better in Numbers
Before we begin this extensive list ????, here’s a pro tip: combine testing types with each other.
A lot of software tests run much better when they’re paired with other methods. These gives you better results, create a much more thorough test, and will help you find your MVPs biggest hiccups quicker.
The 41 Types of Software Testing
No single type of test can provide all the information you need about your product. So, the best course of action would be to combine different tests for your software. Here are 41 of the many types of software testing methods that you can use for your MVP.
Alpha testing comes before beta testing and is conducted internally in a controlled environment to ensure that your MVP can deliver its expected results. Your MVP is brought through a rigorous testing phase to look for bugs, issues, and to test performance in different situations.
To make sure that your efforts to create, develop, and launch ???? an MVP will all be worth it, it’s necessary to conduct acceptance testing. This software evaluation method is the final stage of software development and assesses how well your MVP can carry out its purpose to real-world situations and users. If the test fails, the MVP is generally closed and placed back into development.
Once your MVP is in the end-users hands, you can only provide basic instructions that any user can follow. So, to make sure things run smoothly, you should test whether your MVP can be fully accessed and utilized by the general public. By general public we mean developers, investors, and the intended end-users, including people with disabilities (visual, hearing, physical, cognitive, or learning impairment).
Ad-hoc testing is essentially a software evaluation method that requires no planning, preparation, or discussion before testing. The idea is to “attack” the MVP with the goal of determining possible errors ???? or defects that could arise in the product as early as possible.
Agile MVPs are special in their own way because of the efforts, technology, knowledge, and overall approach in their creation. AAgile testing, which is specifically used in developing agile software, continuously test the MVP throughout the process.
The metrics tested for agile MVPs vary depending on the product’s nature but these are the four key dimensions to focus on:
- Product quality
- Test effectiveness
- Test status
- Test resources
An application programming interface or API consists of different elements such as API response, database, request, and overall application or rendering. API testing is designed specifically to test application programming interface (API) quality. The test goes over how intuitive ????, accessible, and convenient the interface is to use.
Beta testing is the other half of the more commonly known A/B testing. It is one final testing that you need to do for your app or software before finally releasing it to the public. This testing evaluates the full user experience by releasing it to beta testers who will use your MVP for the first time.
Back-end testing aims ???? to address concerns about your MVP’s business and database layers and basically counter-check with the results of your front-end testing. Almost always, front- and back-end testing are used together.
Browser Compatibility Testing
Although Google Chrome is the most popular browser, it’s useful to test your MVP with Firefox, Safari, and more. Browser compatibility testing means checking your MVP across all major browsers. You’ll evaluate the interface, front- and back-end performance, and the general compatibility overall.
Backward Compatibility Testing
???? Backward compatibility testing is typically used when testing newer versions of your MVP. Mainly, it tests the compatibility of the new version with the older or existing versions. This is especially useful if you’re expecting to update your MVP and need to see if the new update will work smoothly with the older version.
Black Box Testing
Black box testing subjects the MVP into a wide range of possible user actions. Whether they were as expected or not, the tester usually has no information about how the MVP works when they perform black box testing. This type of software testing lets testers exercise their freedom to choose what to do with the MVP, but with prior planning, unlike in ad-hoc testing.
Boundary Value Testing
If you’re looking ???? to assess your MVP’s potential against measurable values, the most suitable software testing is the boundary value testing or analysis. For instance, the start and end of the production, lower and upper limits of resources, and other boundaries of the partition. Say, for a particular partition with endpoint values A and B, you’d want to detect as many defects through testing. This test is typically conducted when results of the equivalence partitioning testing are deemed insufficient or needs further validation.
To test the full potential of your MVP, you have to run every possible scenario and command. Branch testing aims to validate your MVP by going through all possible decisions and running every code in your MVP.
Before you can measure your MVP against the others in the market, the first software testing that you should do is comparison testing. This method involves comparing your MVP directly with other similar MVPs to determine well your program performs against the competition. Comparison testing will show your MVPs weaknesses and strengths ????, as well as crucial points that you may have to improve before publishing your app.
Essentially, compatibility testing is an umbrella term for software evaluation methods. In this category, tests aim to determine whether your MVP can perform at its best under all sorts of circumstances and settings. Previously, we have talked about browser and backward compatibility testing, but there are also other types depending on the nature of your MVP.
Some MVPs are only as good as their parts. In such cases, component testing should be included in the top software evaluation methods of priority. This method goes through every component of your MVP and tests their functionality independently. This is done to determine possible breaking points ???? and address them immediately before integrating them as a whole.
E2E or end-to-end testing is a software evaluation method that ensures your MVP can deliver the end-user’s expected results from start to finish. By coming full circle, you can touch upon integration and data integrity issues involving the subsystems. In doing so, you can make the necessary changes to avoid crashing the whole system.
We have mentioned previously that black box testing is a type of software evaluation that involves zero knowledge about the MVP’s internal design. One of the black box ????️ testing techniques is equivalence (class) partitioning.
This method categorizes the objects of your MVP into equivalent or relatively similar partitions and evaluates them as a whole. Depending on how your MVP operates, you should know which results would be good and which would not.
One of the most common types of software testing for agile MVPs is exploratory testing. In this method, the parameters to assess are not pre-planned during product conceptualization. Testers can explore the product simultaneously during execution with the idea that the MVP should keep up and still perform well in the tests.
Functional testing is another encompassing category of software evaluation methods that employ black box testing techniques. Testers are allowed to conduct whatever assessments they think ???? are necessary for the MVP. As long as the tests can validate the MVPs’ expected functions to achieve desired results, sort of like quality assurance.
Graphical User Interface (GUI) Testing
One of the many functional testing methods for your MVP is graphical user interface or GUI testing. The layouts, colors, fonts, labels, texts, captions, and other graphics that you use in creating your MVP can be subjected to either analog recording or object-based recording. Often, third-party companies conduct manual or automatic GUI testing processes for developers and end-users.
Guerilla (UX) Testing
Guerilla testing is one of the bolder techniques in testing your MVP prototype. Basically, developers go to a cafe or a public place to ask people to evaluate their prototypes and film them as they explore ???? the apps. This method may seem daunting, but it gives faster and more reliable results from representatives of the target market themselves.
Happy Path Testing
Unlike the other types of software testing that tackle the MVPs realistically, happy path testing is tightly scripted to simulate the ideal scenario for the MVP. With this approach, developers can measure the optimal outputs for their MVPs in a perfect, everything-goes-well picture. Based on the results of this testing, you can then use other combinations to tweak your MVP and reach these optimum results.
Incremental Integration Testing
As we have mentioned previously, agile MVPs require a little extra TLC to make it the best that it can be. One of the agile MVP-specific testings is incremental integration testing that divides the product into similar or equivalent sections with weighted contributions. The idea ???? is to test per section and layer and identify underlying issues before collating all the data and integrating them to reach a solution.
Install and uninstall testing is a software evaluation packaged deal. You’ll want to make sure that all of your app components are installed and that they can execute tasks properly. That’s why you should conduct install testing. Like so, you perform uninstall testing to make sure that everything is removed successfully from the user’s gadgets.
I&T or integration testing is more commonly conducted towards the end stages of the product development cycle. This software testing aims to evaluate how the subsystem or the whole system performs against the standard or expected metrics. This test is sandwiched ???? between unit testing and validation testing and is usually a non-conditional, must-be-performed test.
Usual software testing methods prioritize specific functions that MVPs should be able to perform. However, load testing is not a functional test. Rather, it is a type of capability testing which measures the MVPs’ performance when multiple users are accessing simultaneously. Overall, this software test ensures that the MVP can still render flawlessly even with a heavier than expected load.
With monkey testing, there are no limits as to what inputs to plugin to your MVP and observe for results. If anything, the singular notion that groups such inputs would be anything that can potentially break the MVP. Your product passes this round of testing if it can withstand issues and errors ???? while still running smoothly.
Mutation can happen with your MVP’s code, so it’s a step ahead if you test for such occurrences. This software evaluation method is a form of white box testing where specific components (i.e. the app’s source code) are altered for the MVP to detect. Specifically, mutation testing as part of unit testing assesses the quality and integrity of the MVP itself, not how it will perform in its applications.
Negative (and Positive)Testing
The goal of testing is to map ????️ out all the areas of your MVP and reduce the gray area for you and its users. Positive testing essentially evaluates whether your app runs as smoothly as it can be with the valid inputs and delivers the expected results. There’s also negative testing that tries to entertain invalid outputs to determine which yields results that are not predetermined. Doing so can help developers prepare for troubleshooting scenarios for the MVP.
For wholesome and more well-rounded testing, every aspect of your MVP should be touched upon. So, this includes other non-functional attributes that make up your product. Load testing is an example from this category, but there are many other software tests that you can carry out depending on the nature of your MVP.
System quality attributes such as speed ????, robustness, reliability, and application size are evaluated in performance testing. In this software evaluation method, you should be able to check if your MVP is responsive and stable enough to carry out its task with the many factors affecting its performance. To name a few indicators, we have server request processing times, acceptable concurrent user volumes, and processor memory consumption.
Recovery testing evaluates how well your MVP can sustain damages and resuscitate after forced software and hardware failures and other related problems. Unlike reliability testing, where you pinpoint a specific stage in the MVP’s execution, recovery testing simulates full system failure.
In regression testing, an intentional change is applied to the whole system while the existing elements are evaluated for functionality and performance. This type of software testing is usually performed when newer versions are underway to completion. The goal is for the old codes to still carry out their tasks well despite the new introductions.
Risk-Based Testing (RBT)
Prioritization of resources is important, especially during the initial stages of your MVP creation. It follows that the succeeding steps, including software testing, should also be carefully selected and allotted with the limited inputs that you have. To help cull down ???? which tests to carry out, risk-based testing is implemented based on the impact and probability of the test or parameter in consideration.
Sanity testing is a subset of regression testing. Aside from the new introduction, sanity testing will ensure that the specific change delivers the expected output or performs the particular function it was set to do. If the prototype fails to pass the sanity test, it follows that developers cannot proceed with building.
Security testing is a non-negotiable type of software testing that anyone who intends to release an MVP should perform. No matter how great the functionality and features of your app are, it will still be a lull product if it has poor or compromised security ????. Also, since the app will be made available to the general public, the app should be resilient enough to counter malicious threats to security to give the users some peace of mind.
You can keep the idea of scaling your MVP up or down during its development and make room for subsequent changes as you go through the life cycle. Granted that your MVP has been successfully launched and thriving in the market, the next type of software testing you should invest in would be for scalability.
Unit testing should not be confused with component testing because the subjects are functional units of the MVP and not the mere parts in this type of software testing. This method operates under the same premise as white box ???? testing, that is, each unit must execute the assigned function flawlessly. Otherwise, the test results allow room for improvement to achieve desired outputs.
User testing is not just software testing but is also an evaluation method to test your MVP. Here, the panel of judges or testers links user testing to usability testing. This type of testing is invaluable as it will tell you how real users will react and use your MVP. Usability testing is closely related to beta testing.
White Box Testing
In contrast with black box testing, white box testing deals with everything that is known and predictable about your MVP. Primarily, these are the internal design, structure, and software coding. This type of software testing is one of the standard tests conducted, especially with developers’ limited resources.
Manual vs. Automated Testing
The numerous types of software testing can be categorized based on who performs the test. In this case, we have manual and automated testing. Manual testing is conducted through human interactions ???? and other man-operated methods. On the other hand, automated testing is carried out with little to no human interaction using machines and other equipment.
You Might Ask
What is STLC in testing?
Software Testing Life Cycle (STLC) comes after the SDLC or the Software Development Life Cycle. It involves the conduct of different types of software testing needed to ensure that the MVP in consideration is actually worth investing in by the stakeholders.
What are testing techniques?
Testing techniques are strategies that you can employ to evaluate your MVP. The idea is to conduct as many tests as possible but as few as you can get by with. In essence, there should be no redundant testing.
Who performs the testing?
Testers can be quality assurance analysts, developers, writers, users, and even machine-generated and coded UIs.
What are the seven principles of testing?
According to this article from Box UK, here are the seven principles of testing:
- Defects are made visible by testing
- There is no such thing as exhaustive testing
- The earlier you start testing, the more resources you can save, including money and time
- Defects are clustered together or are interrelated
- Be cautious of the pesticide paradox
- Depending on the context, a specific testing is needed
- There is no such thing as an error-free MVP
Which testing is done first?
System testing is almost always conducted first to check if your product system can deliver your expected results.
What are STLC and SDLC?
Software Development Life Cycle (SDLC) and Software Testing Life Cycle (STLC) are both sets of different sequential activities that involve your MVP. As their name implies, SDLC is related to software development, while STLC is to the testing portion.
It goes without saying that a combination of different types of software testing can help developers map out as many gray areas as they possibly can for their MVP. While there are core features ✨ that should be working 100 percent of the time, there are compromises that you should be able to settle with about your MVP. Being prepared will help you ease into facing the reality that no app will ever be perfect in all aspects. But as long as yours is functional, reliable, and resilient, it can beat the rest of the competition.
