* the root struct decl name is fully qualified
this prevents error messages containing 'main.main'
* avoid declared here note when file struct is missing a member
It always points at the start of the file which might contain another
container misleading the user.
This will do zig run on the code and expect exit code 0.
// run
Incremental Compilation
Make multiple files that have ".", and then an integer, before the ".zig"
extension, like this:
hello.0.zig
hello.1.zig
hello.2.zig
Each file can be a different kind of test, such as expecting compile errors,
or expecting to be run and exit(0). The test harness will use these to simulate
incremental compilation.
At the time of writing there is no way to specify multiple files being changed
as part of an update.
Subdirectories
Subdirectories do not have any semantic meaning but they can be used for
organization since the test harness will recurse into them. The full directory
path will be prepended as a prefix on the test case name.
Limiting which Backends and Targets are Tested
// run
// backend=stage2,llvm
// target=x86_64-linux,x86_64-macos
Possible backends are:
stage1: equivalent to -fstage1.
stage2: equivalent to passing -fno-stage1 -fno-LLVM.
