There are also negative tests checking code expected to fail compilation. See note about baseline under "Other Tips" below for tests checking expectations against "baseline" (.bsl) files.
-### FSharpQA Suite
-
-The FSharpQA suite relies on [Perl](http://www.perl.org/get.html), StrawberryPerl package from https://strawberryperl.com.
-
-These tests use the `RunAll.pl` framework to execute, however the easiest way to run them is via the `.\build` script, see [usage examples](#quick-start-running-tests).
-
-Tests are grouped in folders per area. Each folder contains a number of source code files and a single `env.lst` file. The `env.lst` file defines a series of test cases, one per line.
-
-Each test case runs an optional "pre command," compiles a given set of source files using given flags, optionally runs the resulting binary, then optionally runs a final "post command".
-
-If all of these steps complete without issue, the test is considered to have passed.
-
-Read more at [tests/fsharpqa/readme.md](tests/fsharpqa/readme.md).
-
-#### Test lists
-
-For the FSharpQA suite, the list of test areas and their associated "tags" is stored at
-
-```shell
-tests\fsharpqa\source\test.lst // FSharpQA suite
-```
-
-Tags are in the left column, paths to to corresponding test folders are in the right column. If no tags are specified, all tests will be run.
-
-If you want to re-run a particular test area, the easiest way to do so is to set a temporary tag for that area in test.lst (e.g. "RERUN") and adjust `ttags` [run.fsharpqa.test.fsx script](tests/fsharpqa/run.fsharpqa.test.fsx) and run it.

-* By default, tests from the FSharpQA suite are run using a persistent, hosted version of the compiler. This speeds up test execution, as there is no need for the `fsc.exe` process to spin up repeatedly. To disable this, uncomment the relevant line (look for `HOSTED_COMPILER`).

## Solving common errors
The following are common errors that users have encountered while running tests on their system.
### Error that a file cannot be accessed
-The build often leaves dangling processes like `HostedCompilerServer.exe`, `VBCSCompiler.exe` or `MSBuild.exe`. In [Process Explorer](https://learn.microsoft.com/sysinternals/downloads/process-explorer) you can see these processes having no parent process anymore. You can also use this to kill such processes.
