Recipe source
​GitHub, Issue Tracker, Maven Central​
groupId: org.openrewrite.recipe
artifactId: rewrite-testing-frameworks
version: 2.1.0
This recipe is composed of more than one recipe. If you want to customize the set of recipes this is composed of, you can find and copy the GitHub source for the recipe from the link above.
Usage
This recipe has no required configuration options. It can be activated by adding a dependency on org.openrewrite.recipe:rewrite-testing-frameworks:2.1.0 in your build file or by running a shell command (in which case no build changes are needed):
Gradle
Gradle init script
Maven POM
Maven Command Line
Moderne CLI
1.Add the following to your build.gradle file:
build.gradle
plugins {
    id("org.openrewrite.rewrite") version("6.5.6")
}
​
rewrite {
    activeRecipe("org.openrewrite.java.testing.hamcrest.MigrateHamcrestToAssertJ")
}
​
repositories {
    mavenCentral()
}
​
dependencies {
    rewrite("org.openrewrite.recipe:rewrite-testing-frameworks:2.1.0")
}
2.Run gradle rewriteRun to run the recipe.
1.Create a file named init.gradle in the root of your project.
init.gradle
initscript {
    repositories {
        maven { url "https://plugins.gradle.org/m2" }
    }
    dependencies { classpath("org.openrewrite:plugin:6.5.6") }
}
rootProject {
    plugins.apply(org.openrewrite.gradle.RewritePlugin)
    dependencies {
        rewrite("org.openrewrite.recipe:rewrite-testing-frameworks:2.1.0")
    }
    rewrite {
        activeRecipe("org.openrewrite.java.testing.hamcrest.MigrateHamcrestToAssertJ")
    }
    afterEvaluate {
        if (repositories.isEmpty()) {
            repositories {
                mavenCentral()
            }
        }
    }
}
2.Run gradle --init-script init.gradle rewriteRun to run the recipe.
1.Add the following to your pom.xml file:
pom.xml
<project>
  <build>
    <plugins>
      <plugin>
        <groupId>org.openrewrite.maven</groupId>
        <artifactId>rewrite-maven-plugin</artifactId>
        <version>5.13.0</version>
        <configuration>
          <activeRecipes>
            <recipe>org.openrewrite.java.testing.hamcrest.MigrateHamcrestToAssertJ</recipe>
          </activeRecipes>
        </configuration>
        <dependencies>
          <dependency>
            <groupId>org.openrewrite.recipe</groupId>
            <artifactId>rewrite-testing-frameworks</artifactId>
            <version>2.1.0</version>
          </dependency>
        </dependencies>
      </plugin>
    </plugins>
  </build>
</project>
2.Run mvn rewrite:run to run the recipe.
shell
mvn -U org.openrewrite.maven:rewrite-maven-plugin:run \
  -Drewrite.recipeArtifactCoordinates=org.openrewrite.recipe:rewrite-testing-frameworks:RELEASE \
  -Drewrite.activeRecipes=org.openrewrite.java.testing.hamcrest.MigrateHamcrestToAssertJ
You will need to have configured the Moderne CLI on your machine before you can run the following command.
shell
mod run . --recipe MigrateHamcrestToAssertJ
