Hi Maxence,

Something I found useful when working with glsl tests is when you create
a summary as Marek describes you can click on a test and it will give
you the command used to run that test.

For example a compile test:
/home/timothy/piglit/Mesa_arrays_of_arrays_piglit/bin/glslparsertest
tests/spec/glsl-1.40/compiler/gl_FragCoord.frag pass 1.40 

You can then easily run glslparsertest in gdb and pass in the required
parameters for debugging.

Also something useful to note is that its easy to run only the tests you
need to.

For example:
./piglit-run.py -t glsl-1.40 tests/all.tests results
Will run all glsl-1.40 tests

./piglit-run.py -t glsl-1.40/compiler tests/all.tests results
Will run only the glsl-1.40 compiler tests

./piglit-run.py -t glsl-1.40/compiler/gl_F tests/all.tests results
Will run only compiler tests that start with gl_F

./piglit-run.py -t glsl-1.40/compiler/gl_FragCoord.frag tests/all.tests
results
Will only run gl_FragCoord.frag

I hope this information is useful.
