How Monokulo is tested

Monokulo handles other people’s money, so it gets tested hard. Every change runs more than 2,600 automatic tests. Every night, two kinds of robot tester invent thousands of strange situations and check that no payment goes missing. This page rebuilds itself from those runs. Open any section to see the details.

Coverage

While the tests run, a tool watches which lines of code actually get used. Code that no test ever runs is where bugs can hide. Higher is better, but 100% isn’t the goal: some code, like the stress-test tools, never ships. A branch is each way an if can go. Open a crate (a package of Rust code) to see its files, lowest first.
