Once you understand why you want to practice test automation, there is only one question left - how to do that? Unit tests, Component tests, End-to-End tests, Continuous integration, Code review, Tools...

1. Automated testing
How?

2. unit tests
component tests
integration tests
end-to-end and smoke tests
acceptance and contract tests
code review
continuous integration and deployment

5. 4 clear blocks: setup, operation, validation, teardown
Single claim per test, description should not contain “and”
Independently executable
Unit tests

6. Test descriptions first, then code and tests in parallel
Code first, then tests
Pure TDD (single failing test – single feature – refactor – repeat)
Unit tests

10. Service1 Service2mock

Component tests

11. Cover interface
Cover possible behaviours of dependencies
Common mock for positive scenarios
Ad-hock mocks for error scenarios
Possible duplication of some unit tests
Mock databases with in-memory databases.
Component tests

14. Cover interface between units
E.g. if plugins can be plugged in
Often can be omitted because of component tests cover it
Sometimes it may be efficient to create integration tests instead of unit tests
Integration tests

17. ✓ unit tests
✓ component tests
✓ integration tests
end-to-end and smoke tests
acceptance and contract tests
code review
continuous integration and deployment

18. Use staging environment
Stable test data set in database
(alternative would be setup and teardown as part of test)
Mock external http-based services using Robohydra
Create page models for abstracting interaction with html/css
Protractor for running tests in browser
End-to-end tests for HTTP API can be done using mocha, much faster
End-to-end tests

20. Technically same as end-to-end tests
Use in production environment right after deployment
Very limited number of tests, just to validate the deployment success
Smoke tests

21. Link and track with business requirements
Does not have to be end-to-end test
Acceptance tests

22. Set of customer-specific requirements
If the customer vanishes, the tests can be removed
Coverage tools can be used to find code that no customer requires
Contract tests

23. ✓ unit tests
✓ component tests
✓ integration tests
✓ end-to-end and smoke tests
✓ acceptance and contract tests
code review
continuous integration and deployment

24. No seniority – everybody can and has to review
Are the tests descriptions working as a specification?
Has the author revised the existing tests for the entire unit or just added new?
Readability of both code and tests.
Third eye-pair code review for pair programming.
Code review

25. Continuous integration and deployment
Development
and tests
(feature
branch)
Code
review
Tests
(feature
branch) Merge to
master
Tests
(master)
End-to-end
tests
Deploy to
production
Deploy to
stage
Smoke
tests
Development CI (docker) Stage Production

26. Protractor – browser end-to-end test runner
Karma – JavaScript unit test runner
Mocha + chai – JavaScript unit test framework
Istanbul – coverage
Nock – http interception for nodejs
Sinon – mocking tool for JavaScript objects and libraries
Robohydra – webserver for mocking
Phabricator + arcanist – code review
Jenkins – continuous integration
