| # difftest | ||
|
|
||
| This tool finds tests which were changed since a previous git revision. | ||
|
|
||
| ## Usage | ||
|
|
||
| To see changes: | ||
|
|
||
| ``` | ||
| difftest diff --path . --branch master | ||
| ``` | ||
|
|
||
| To get `go test` flags to run only newly appeared tests: | ||
|
|
||
| ``` | ||
| difftest test --path . --branch master --exclude-updates | ||
| ``` | ||
|
|
||
| ## How it works | ||
|
|
||
| 1. Calls `git diff $(git merge-base --fork-point <branch>)` | ||
| 2. Filters all added/modified files ending with `_test.go`. | ||
| 3. Builds a map of `Test*` methods in every file. | ||
| 4. Calculates `SHA1` hash of each method body. | ||
| 5. Does the same for the counterpart files at the fork point. | ||
| 6. Compares the results. If a method was not there previously, it's marked as new. If a method's contents was changed, it is marked as changed. | ||
|
|
||
| ## `testify/suite` support | ||
|
|
||
| 1. Tool detects suite start signatures like the following: | ||
|
|
||
| ``` | ||
| func TestSingleSuite(t *testing.T) { suite.Run(t, &SingleSuite{}) } | ||
| ``` | ||
| where `suite` references to `testify/suite` package, and `t` references `testing` package. | ||
| 2. All methods related to a single suite must be in the same package (directory). | ||
| 3. All suite parts must redside in a files matching `*_test.go` pattern. | ||
| 3. If a test method has a receiver, which was not detected as a `testify/suite` previously, such method got skipped. |
