5.19.4. Writing New Tests

As mentioned previously, all new test files need to be in the proper place for the build system to find them. New tests for additional functionality outside of the core should be added to the layer that adds the functionality, in layer/lib/oeqa/runtime (as long as BBPATH is extended in the layer's layer.conf file as normal). Just remember that filenames need to map directly to test (module) names and that you do not use module names that collide with existing core tests.

To create a new test, start by copying an existing module (e.g. syslog.py or gcc.py are good ones to use). Test modules can use code from meta/lib/oeqa/utils, which are helper classes.

Note

Structure shell commands such that you rely on them and they return a single code for success. Be aware that sometimes you will need to parse the output. See the df.py and date.py modules for examples.

You will notice that all test classes inherit oeRuntimeTest, which is found in meta/lib/oetest.py. This base class offers some helper attributes, which are described in the following sections:
