The design for running all Crashpad unit tests on Chromium’s try- and buildbots involves pulling all tests into a single monolithic crashpad_tests executable. Many Crashpad tests base the name of their child executables or modules on the name of the main test executable. Since the main test executable will have a different name in the in-Chromium build, knowledge of the test executable name (referred to as “module” here) needs to be added to the tests themselves. This introduces TestPaths::BuildArtifact(), which allows the module name to be specified. For Crashpad’s standalone build, the module name is verified against the main test executable’s name. TestPaths::BuildArtifact() can also locate paths in the alternate 32-bit output directory for 64-bit Windows tests, taking on the responsibility for what the new (5e9ed4cb9f69) TestPaths::Output32BitDirectory(), now obsolete, did.
