Compiler warning overwrites failing test results in test results pane

[rvermeulen]

Describe the bug

When you execute a QL test from the test explorer, and the compilation of the tested query has warnings, such as unused predicates or deprecated elements, then the diff view of a failed test is not visible.

Version
The CodeQL and VS Code version in which the bug occurs.

CodeQL extension version: 1.12.2
CodeQL CLI version: 2.14.6
Platform: darwin x64

To reproduce

1. Create a failing QL test of a query with an unused predicate or deprecated module.
2. Execute the test

Expected behavior

The test explorer shows the diff of the expected and actual output, in addition to the compiler warnings.

FWIW, I've also heard Microsoft people mention this before

Thanks for the report. I have opened a ticket internally to track this.

This will be fixed in the next release of the extension. Please note that the compiler warning will still show up in the test output as this functionality is used for testing CodeQL itself as well:
