custom zig test flags?

[nnnewb]

I’m working on a hobby project with mixed Zig and C programming.

The "Run Test" button provided by the vscode-zig extension fails to compile when the project requires linking to C libraries.

Run Test

Command failed: C:\Users\PC\scoop\shims\zig.EXE test --test-filter keyword d:\projects\starlight\src\parser\tokenizer.zig
D:\projects\starlight\src\parser\tokenizer.zig:1:11: error: C import failed
D:\projects\starlight\src\parser\tokenizer.zig:1:11: note: libc headers not available; compilation does not link against libc
C:\Users\PC\AppData\Local\zig\o\e3f7f0f004f28d89132de840b129a16d\cimport.h:1:10: error: 'parser/token.h' file not found

Debug Test

Command failed: C:\Users\PC\scoop\shims\zig.EXE test d:\projects\starlight\src\parser\tokenizer.zig --test-filter keyword --test-no-exec -femit-bin=d:\projects\starlight\zig-out\tmp-debug-build\bin\test-tokenizer
D:\projects\starlight\src\parser\tokenizer.zig:1:11: error: C import failed
D:\projects\starlight\src\parser\tokenizer.zig:1:11: note: libc headers not available; compilation does not link against libc
C:\Users\PC\AppData\Local\zig\o\d88f36432145d60ca7a16061bebdc714\cimport.h:1:10: error: 'parser/token.h' file not found

However, running the command zig test -lc -Isrc src/parser/tokenizer.zig src/parser/lexer.c in the command line compiles and runs the tests without any issues.

PS D:\projects\starlight> zig test -lc -Isrc src/parser/tokenizer.zig src/parser/lexer.c
All 4 tests passed.

I noticed the vscode-zig extension doesn't support custom flags for zig test. Could you please consider adding this feature? It would be very helpful.

This should be implemented by running the tests with the build system which is tracked in #390.
