When running with this avocado parameter, bitbake is called with "-g" prior to executing the build. By that, a dependency graph of what bitbake will execute is dumped that tremendously helps in identifying what we test. This further helps developers to strip down tests to the features that should be tested by locating unwanted tasks that are pulled in via transitive dependencies. The feature is modeled as a test function itself, so it can later be extended to write parser-only tests or graph analysis tests. Signed-off-by: Felix Moessbauer <felix.moessbauer@siemens.com> --- Changes since v2: - do not reconfigure job if not explicitly requested - if reconfiguring, also pass kwargs - copy out the pn-tasklist as well Changes since v1: - working version. v1 was the wrong commit.
