power_assert
Power Assert for Elixir: enhances ExUnit test output by showing evaluation results of each expression in assertions.
What is power_assert?
Power Assert is an Elixir library that enhances ExUnit's assertion output by showing the evaluation results of each sub-expression within test assertions. It helps developers understand exactly why a test failed by revealing intermediate values without requiring changes to test logic. This makes debugging complex assertions significantly easier.
Elixir developers using ExUnit for testing who want better debugging insights from test failures, particularly those working with complex assertions or nested expressions.
Developers choose Power Assert because it provides dramatically better test failure diagnostics with zero code changes—simply replace one import statement. Unlike traditional assertion libraries, it shows the complete evaluation chain, making it ideal for debugging complex logical expressions.
