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 <dhiller@redhat.com>
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 <dhiller@redhat.com>
initial approach to generate classification for test flakiness Signed-off-by: Daniel Hiller <dhiller@redhat.com>
also finding test file by test name now works Signed-off-by: Daniel Hiller <dhiller@redhat.com>

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 <dhiller@redhat.com>
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 <dhiller@redhat.com>

adds a handler for /stats that emits statistics for the model data. Signed-off-by: Daniel Hiller <dhiller@redhat.com>
Since we can't rely on the name alone we add support for finding tests by test_id. Signed-off-by: Daniel Hiller <dhiller@redhat.com>

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 <dhiller@redhat.com>
