There are 100+ backend tests and each requires 400+ MB of disk space when statically linked (the default). This requires a large amount of disk space and adds considerable link time. This introduces a framework to link multiple backend tests into a single executable. Currently it does this for several tests in be/src/util. It saves about 10GB of space. It maintains several of the same properties that the current tests have: 1. "make <testname>" rebuilds that test. 2. It generates an executable shell script with the same name as the original backend test that runs the same subset of tests. 3. It generates JUnitXML and log files with names that match the test name. 4. One can run the shell script with "--gtest_filter" and run a subset of the tests. 5. ctest commands such as ctest -R continue to function. It validates at build time that every test linked into the unified executable is covered by an equivalent test filter pattern. This means that every test in the unified executable will run as part of normal testing. Introducing the framework along with a limited number of trial backend tests gives us a chance to evaluate this change before continuing to convert tests.
