How do I set up code coverage tools for my project?

To set up code coverage tools, you first need to choose a tool that fits your programming language. Popular options include Istanbul for JavaScript, JaCoCo for Java, and Coverage.py for Python. Do you have a specific language in mind?

I'm using Java. What steps should I follow?

For Java, you can use JaCoCo. First, add the JaCoCo plugin to your build tool, like Maven or Gradle. Then, configure it to run during your test phase. Would you like detailed steps for Maven or Gradle?

Can you provide the Maven configuration?

Sure! In your pom.xml, add the JaCoCo plugin under the <build> section. Here's a basic configuration:

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.8.7</version>
    <executions>
        <execution>
            <goals>
                <goal>prepare-agent</goal>
            </goals>
        </execution>
        <execution>
            <id>report</id>
            <phase>test</phase>
            <goals>
                <goal>report</goal>
            </goals>
        </execution>
    </executions>
</plugin>

This will prepare the agent and generate a report after your tests run.

Thanks! How do I view the coverage report?

After running your tests, JaCoCo will generate a report in the target/site/jacoco directory. You can open the index.html file in a web browser to view the coverage details.
