Testing

  • What is automated testing, and what is the difference from manual testing?
  • What is unit-test?
  • What is TDD?
  • What is the advantage of TDD? Why write tests first and then code?
  • What are regression bugs and how do automated tests help solve them?
  • Why do side effects impair code testability?
  • What is mock and when should they be used?
  • What is a spy and when should they be used?
  • Is it worth testing private class methods? Why?
  • Why group separate tests inside unit tests?
  • How long should an ideal work cycle last: _ writing a test -> changing functionality -> refactoring_?
  • What libraries are there for creating tests and running them (and how do they differ from each other)?
  • How do tests help newcomers enter the project?
  • How do tests help in documenting a project?
  • How do tests speed up getting feedback from the work done and why is this feedback important?
  • What steps in manual testing help avoid unit tests?
  • Why make tests run fast?
  • How to ensure that test errors are as obvious as possible?
  • Do I need to automatically test the tests themselves?
  • What are the boundary conditions? Why test them?
  • What is heisenbug? What are the ways to debug them?
  • What is fixture?
  • What is code coverage with tests? What tools are there for analyzing it?
  • How are unit tests different from integration tests? Why is integration harder to write and maintain?
  • Why pay attention to patterns when tests fail? How can analysis of which particular test combination fall off help?
  • How do tests help in designing? Why is module testability an excellent indicator of "code cleanliness"?
  • How do tests help with refactoring?
  • What are the advantages of the rule of one concept per unit test?
  • What are the advantages of tests isolated from each other?
  • How to find a balance between the number of tests and code coverage? What problems can be caused by an excessive number of unit tests?
  • What is a test pyramid? What role do tests play there? What role does static code analysis play there?
  • Are types a complete replacement for unit tests? Why?
  • What are end-to-end tests? What is the difference from integration?
  • When do tests really slow down development, and when do they speed up?
  • Are tests a full part of the system and code base?
  • Why is testing becoming less convenient if you test not only public but also private methods?
  • What are Test Double and Fake? What is the difference from Mock and Stub?
  • What is the difference between testing with behavior verification and state verification?
  • Why does the application of Mocks provoke behavior verification?
  • What are Solitary and Sociable tests? What are the benefits of solitary tests? Are there any benefits to Sociable tests?
  • Why does Mocks simplify outside-in design?
  • Why strive to ensure that tests can be run as conveniently as possible and with just one team?
  • Is it worth writing "training" integration tests that are run only manually and only for testing an external API (for example, the Web API Github)?
