## Do
|
||
|
|
1. Name your files <description>.tests.ps1
|
||
|
|
2. Keep tests simple
|
||
|
|
1. Test only what you need
|
||
|
|
2. Reduce dependencies
|
||
|
|
3. Be sure to tag your Describe blocks with "inner" and "outer"
|
||
|
|
4. Make sure that Describe/Context/It descriptions are useful
|
||
|
|
1. The error message should not be the place where you describe the test
|
||
|
|
5. Use "Context" to group tests
|
||
|
|
1. Multiple Contexts can help you group your test suite into logical sections
|
||
|
|
6. Use BeforeAll/AfterAll/BeforeEach/AfterEach instead of custom initiators
|
||
|
|
7. Use Try-Catch for expected errors and check $_.fullyQualifiedErrorId
|
||
|
|
8. Loop It blocks for checking multiple properties
|
||
|
|
9. Use code coverage functionality where appropriate
|
||
|
|
10. Use Mock functionality when you don't have your entire environment
|
||
|
|
11. Avoid free code in a Describe block
|
||
|
|
1. Use `[Before|After][Each|All]` _see Free Code in a Describe block_
|
||
|
|
|
||
|
|
## Don't
|
||
|
|
1. Have too many evaluations in a single It block
|
||
|
|
1. The first "Should" failure will stop that block
|
||
|
|
2. Don't use "Should" anywhere but within an "It" Block
|
||
