| # Speedtest |
| `SPEEDTEST` is the tool we use to measure lint's performance, it works by executing the same test several times. |
| |
| It's useful for measuring changes to current lints and deciding if the performance changes too much. `SPEEDTEST` is |
| accessed by the `SPEEDTEST` (and `SPEEDTEST_*`) environment variables. |
| |
| ## Checking Speedtest |
| |
| To do a simple speed test of a lint (e.g. `allow_attributes`), use this command. |
| |
| ```sh |
| $ SPEEDTEST=ui TESTNAME="allow_attributes" cargo uitest |
| ``` |
| |
| This will test all `ui` tests (`SPEEDTEST=ui`) whose names start with `allow_attributes`. By default, `SPEEDTEST` will |
| iterate your test 1000 times. But you can change this with `SPEEDTEST_ITERATIONS`. |
| |
| ```sh |
| $ SPEEDTEST=toml SPEEDTEST_ITERATIONS=100 TESTNAME="semicolon_block" cargo uitest |
| ``` |
