----------------------------------
Summary: Enable resource files to be loaded easily in unit tests
Key: MINIFI-290
URL: https://issues.apache.org/jira/browse/MINIFI-290
Project: Apache NiFi MiNiFi
Issue Type: Improvement
Components: C++, Testing
Reporter: Kevin Doran
Priority: Minor
As part of MINIFI-275, unit test cases were introduced that rely on YAML
configuration input. Currently, the YAML is defined as string constants in the
test cases (see [1]).
During peer review of MINIFI-275, it was suggested by [~phrocker] to move the
YAML inputs to resource files and load them for the test. This ticket captures
that improvement which will cleanup the unit test code by making the YAML input
easier to locate and maintain.
As part of this, we need a clean way to set resource file locations in CMAKE so
that they are easily available in ctest test cases. As the `test` target which
invokes ctest is a builtin/standard CMAKE generated target, it is more limited
in its configurability for items such as command line arguments [2] and
environment variables (SET (CTEST_ENVIRONMENT ...) apparently does not work in
CMakeLists.txt files, only when CMake is invoked via the CLI. This needs some
more experimenting / digging into with our specific version of CMAKE before we
decide on an approach for implementation.
