Usage
ava [<file|directory|glob> ...]
Options
--init Add AVA to your project
--fail-fast Stop after first test failure
--serial, -s Run tests serially
--tap, -t Generate TAP output
--verbose, -v Enable verbose output
--no-cache Disable the transpiler cache
--no-power-assert Disable Power Assert
--color Force color output
--no-color Disable color output
--match, -m Only run tests with matching title (Can be repeated)
--watch, -w Re-run tests when tests and source files change
--timeout, -T Set global timeout
--concurrency, -c Max number of test files running at the same time (Default: CPU cores)
--update-snapshots, -u Update snapshots
Examples
ava
ava test.js test2.js
ava test-*.js
ava test
ava --init
ava --init foo.js
Default patterns when no arguments:
test.js test-*.js test/**/*.js **/__tests__/**/*.js **/*.test.js
