Creates the first command `cannier extract` that defines the interface of the feature vector. Nearly all of the values returned are mocked. Signed-off-by: Daniel Hiller <[email protected]>
Adds retrieval of the ast.CallExpr that is the test declaration by name. Refactoring: moves outline generation into robots/pkg/ginkgo Signed-off-by: Daniel Hiller <[email protected]>
initial approach to generate classification for test flakiness Signed-off-by: Daniel Hiller <[email protected]>
also finding test file by test name now works Signed-off-by: Daniel Hiller <[email protected]>
Signed-off-by: Daniel Hiller <[email protected]>
We now have the commands: * `generate model` - saves the model data to disk * `generate classes` * `host model` - takes a data file and serves the model Signed-off-by: Daniel Hiller <[email protected]>
plan: create a GET handler that gives a statistical overview about the model data, i.e. * number of classes and their appearance * min, max, average of each feature Signed-off-by: Daniel Hiller <[email protected]>
Signed-off-by: Daniel Hiller <[email protected]>
adds a handler for /stats that emits statistics for the model data. Signed-off-by: Daniel Hiller <[email protected]>
Since we can't rely on the name alone we add support for finding tests by test_id. Signed-off-by: Daniel Hiller <[email protected]>

Creates the required data we need for mapping tests towards file changes. This change holds an automatic expansion of a git repository inside testdata so that we can unit test git operations. Also updates the unit tests for blame. Signed-off-by: Daniel Hiller <[email protected]>
Adds the `extract changed-tests` command which determines for a given revision range the changes to tests inside a code base. Output is the names of the changed tests as well as the ginkgo node data for the paths to each changed test. Paths are expanded from the ginkgo tree, which means each path describes exactly one test.

What this PR does / why we need it:
Implements the code parts required for the CANNIER approach 1 .

Note: most of the values returned are mocked currently.
