| 6 | What are these tests? |
| 7 | --------------------- |
| 8 | |
| 9 | Unit tests are the self checks for Tempest. They provide functional |
| Jordan Pittier | 74a56ab | 2017-04-26 16:46:20 +0200 | [diff] [blame] | 10 | verification and regression checking for the internal components of Tempest. |
| 11 | They should be used to just verify that the individual pieces of Tempest are |
| Matthew Treinish | 32d3570 | 2013-08-13 11:59:06 -0400 | [diff] [blame] | 12 | working as expected. They should not require an external service to be running |
| Jordan Pittier | 74a56ab | 2017-04-26 16:46:20 +0200 | [diff] [blame] | 13 | and should be able to run solely from the Tempest tree. |

| Jordan Pittier | 74a56ab | 2017-04-26 16:46:20 +0200 | [diff] [blame] | 15 | Why are these tests in Tempest? |
| Matthew Treinish | 32d3570 | 2013-08-13 11:59:06 -0400 | [diff] [blame] | 16 | ------------------------------- |
| 17 | These tests exist to make sure that the mechanisms that we use inside of |
| Jordan Pittier | 74a56ab | 2017-04-26 16:46:20 +0200 | [diff] [blame] | 18 | Tempest are valid and remain functional. They are only here for self |
| 19 | validation of Tempest. |

| 22 | Scope of these tests |
| 23 | -------------------- |
| 24 | Unit tests should not require an external service to be running or any extra |
| 25 | configuration to run. Any state that is required for a test should either be |
| 26 | mocked out or created in a temporary test directory. (see test_wrappers.py for |
| 27 | an example of using a temporary test directory) |
