# Massive testdata updating
There is a handler [UpdateTestDataHandler](../tests-common-new/tests/org/jetbrains/kotlin/test/backend/handlers/UpdateTestDataHandler.kt),
which can be used to update all testData. It is disabled by default. It can be enabled by either changing code,
or by passing system property `kotlin.test.update.test.data`.
For example, to update all IR text test data by the output of the JVM backend, you can use:
```bash
./gradlew -Pkotlin.test.update.test.data=true :compiler:fir:fir2ir:test --tests "org.jetbrains.kotlin.test.runners.ir.FirPsiJvmIrTextTestGenerated" --continue
```
# Code style
Please keep your abstract test runners as simple as possible. Ideally each abstract test runner should contain **only** test configuration with DSL and nothing else. All services implementations should be declared in separate files.
