Introduction to Gradle Test Logger Plugin

The Gradle Test Logger Plugin is a robust tool designed to enhance the developer's console experience while running tests. It offers beautifully formatted logs, making the test results easier to read and understand.

Key Features

Beautiful Logs: The plugin provides visually appealing logs in the console, displaying test results in various themes, such as 'standard' and 'mocha'.
Customization Options: Users can customize the test logs to meet their specific needs, with options to show or hide exceptions, stack traces, and standard streams.
Theme Variations: Several themes are available to suit different preferences, from plain text to colorful, symbol-infused logs.

Runtime Configuration: Users can override configurations at runtime using system properties, offering flexibility in controlling how logs are displayed.

Installation and Setup

To use the Gradle Test Logger Plugin, users have two primary installation methods:

Using the Plugins DSL: This method simplifies the integration by including the plugin directly in the plugins section of the build.gradle file:
```
plugins {
    id 'com.adarshr.test-logger' version '4.0.0'
}
```

Using Legacy Plugin Application: This method involves declaring the plugin dependency in the buildscript block:

buildscript {
    repositories {
        maven {
            url 'https://plugins.gradle.org/m2/'
        }
    }
    dependencies {
        classpath 'com.adarshr:gradle-test-logger-plugin:4.0.0'
    }
}
apply plugin: 'com.adarshr.test-logger'

Configuration Details

The plugin offers a rich set of configurations:

Themes: Switch between themes like 'plain', 'standard', and 'mocha' to suit different preferences for color and symbols.
Exception and Stack Trace Visibility: Configure whether to display exceptions, stack traces, and causes, thus customizing the verbosity of the log output.
Slow Test Threshold: Define what qualifies as a 'slow' test by setting a threshold for test execution durations, allowing greater control over identifying performance bottlenecks.
Log Levels and Summaries: Adjust log levels for more granular control over output visibility, and decide whether to display summaries of test results.

Special Features

Compatibility and Versions: The plugin supports various Gradle versions, with a compatibility matrix ensuring that users choose the right plugin version for their Gradle setup.
Kotlin DSL Support: It also supports configuration using the Kotlin DSL, ensuring versatility across different project setups.
Integration Considerations: While it's compatible with JUnit 5 via Gradle's native setup, it does not work with the deprecated junit-platform-gradle-plugin, emphasizing the need for updated practices.

FAQs and Troubleshooting

The plugin is designed to work seamlessly across different environments, with specific instructions for optimal performance on systems like Windows. Troubleshooting steps are provided to tackle common issues, such as seeing duplicate output or configuring settings for parallel execution.

Conclusion

The Gradle Test Logger Plugin is an indispensable tool for developers seeking to improve the readability and manageability of their test logs. With its extensive customization options and support for modern development workflows, it stands out as a must-have enhancement for any Gradle-based project.
