A regression test. Very fragile.
It generates a jogfile for metrics_test.yaml and compares it
byte-for-byte with an expected output file.
Also, part one of a two-part test.
The generated jogfile is consumed in Rust_TestJogfile in t/c/g/tests/gtest/test.rs
This is to ensure that the jogfile we generate in Python can be consumed in Rust.
To generate new expected output files, set `UPDATE_EXPECT=1` when running the test suite:
UPDATE_EXPECT=1 mach test toolkit/components/glean/pytest
