5 Types of Testing Software Every Developer Needs to Know!

Software testing is a critical part of programming, and it is important that you understand these 5 types of testing that are used in software development. In this video, I go over the importance of the software testing pyramid and explain how the testing changes at each level. I also touch on MC/DC code coverage, which is critical if you every want to work in defence or aviation.

Thank you!! So helpful!

[@NaftuliSinger]

Great straight to the point video! Thank you!

[@yassinesedjari1880]

Thanks Alex, concise and straight to the point explanation. 👌

[@alexhyettdev]

You're welcome, I hope it was useful for you.

[@codewithbru]

This video was very useful, thank you very much! Your editing is amazing :)

[@alexhyettdev]

Thank you! I am glad it was useful.

[@kcayushma]

Got the concept in 6 mins vs 3hr of lectures and mediocre bragging thank you 🙏

[@user-ek7bv1de2k]

Alex thank you for your video, it was very useful. Could you please give an example of a component testing for example on Facebook login page’s.

[@khushsanghavi8805]

excellent explanation...just one doubt...what is the exact difference between component and integration testing then?

[@alexhyettdev]

So component testing is testing a component in isolation from everything else. So think of an API but with any external API calls and the database mocked out. Integration testing is testing multiple components together.

[@kodnzikus]

Good stuff!

[@alexhyettdev]

Thanks! I am glad you enjoyed.

[@AnkitTiwari-dq7qm]

Good explanation❤️

[@alexhyettdev]

Thank you, I am glad you liked it.

[@markodjordjevic6920]

Great video, I have just one question. What are API tests ? They seem to me like they are actually component tests, but these naming conventions can be quite confusing.

[@zentelia3666]

API testing, a subset of component testing, focuses on evaluating the functionality, reliability, performance, and security of application programming interfaces (APIs) to ensure seamless communication between different software components and systems. Basically in Component or Integration testing, you use the program API to do your test.

[@terry-]

Great!

[@ukaszkiepas57]

thanks a lot

[@alexhyettdev]

You’re welcome!

[@melk48111]

what about regression test?

[@danieloyagha100]

Awesome

[@coachobispersonalworkoutti2223]

jUST ONE QUESTION ARE THESE THE LEVELS OF TESTING OR TYPES OF TESTING

[@yantaosong]

thanks ,Alex , but can't understand the component test .

[@Lu149]

think if you're testing a car. You would want to test the engine on its own (component testing). The individual parts of the engine will also need to be tested i.e fuel injectors (unit testing). Then you want to test how the engine fits into the car model (integration testing)

[@markveszelka376]

Interestingly, you mention unit testing and component testing as different levels of the pyramid, but regarding the ISTQB Foundation Level Syllabus: v 4.0: 'Component testing (also known as unit testing) focuses on testing components in isolation' v 3.1.1: 'Component testing (also known as unit or module testing) focuses on components that are separately testable.' Great video anyway! :)

[@chenfry8849]

Your MCDC explanation is incorrect, you would need 4 for this senario. you need to show how each variable affects the outcome. The coverage you explained is predicate coverage, which is higher subsumption than MCDC.
