Adding `name` to `glob_lit_tests` will make it conform with other implementations of `glob_lit_tests` out there. If someone uses this repo while providing a different version of `glob_lit_tests` that requires a name, those build rules will become invalid.

`lit` reference:

https://llvm.org/docs/CommandGuide/lit.html

This will generate three types of rules:
|
|
1. For each test file, a rule with ".test" at the end. For example,
|
|
"foo/bar/baz.carbon" will generate ":foo/bar/baz.carbon.test"
|
|
2. If any test exists in subdirectory, a test_suite is generated for each
|
|
directory. For example, ":foo" will run all tests under directory "foo",
|
|
and ":foo/bar" will run all tests under "foo/bar".
|
|
3. A test_suite containing all tests. The name of this will be the "name"
|
|
arg passed to the glob_lit_tests rule.
|
|
|
|
Args:
|
|
name: The name of the test_suite rule to generate for running all tests.
|
|
driver: The path to the lit config.
|
|
data: A list of tools to provide to the tests. These will be aliased for
|
|
execution.
|
|
test_file_exts: A list of extensions to use for tests.
|
|
exclude: A list of paths to exclude from the glob.
|
|
**kwargs: Any additional parameters for the generated py_test.
