SoCRATES

SoCRATES is an IntelliJ IDEA plugin to detect test smells in Scala/SBT projects.

It automatically detects and reports on 6 test smells including 4 variants of General Fixture.

Test class smells	Test case smells
Global Fixture (General Fixture)	Assertion Roulette
Lazy Test	Sensitive Equality
	Eager Test
	Loan Fixture (General Fixture)
	With Fixture (General Fixture)
	Fixture Context (General Fixture)
	Mystery Guest

Compilation (optional)

1. Clone the project to ~/socrates.
2. Open the project in IntelliJ IDEA.
3. If necessary, adapt the versions of the IntelliJ plugin/IDE. (Search for "This version can be changed" in build.gradle)
4. Execute the Gradle task assembly.
5. A succesful compilation results in a .zip file located at ~/socrates/build/distributions/socrates-1.0-SNAPSHOT.zip.

Installation

1. Go to IntelliJ IDEA -> Preferences -> Plugins -> Install Plugin from Disk...
2. Navigate to ~/socrates/build/distributions/socrates-1.0-SNAPSHOT.zip.
3. Restart IntelliJ IDEA to complete the installation.

Usage

1. Open any project in IntelliJ IDEA.
2. Go to Analyze -> Detect Test Smells or Other -> Detect Test Smells (depending on the IntelliJ version)
3. A dialog with the following options appears
   • Java Runtime should point to the rt.jar file;
   • Ivy2 should point to the ivy2 cache (multiple directories should be seperated by :);
   • SBT Home should point to the SBT binary;
   • any additional SBT option can be define in SBT Options. For example, we recommend to increase the available memory for large projects.
4. Press the Analyze button to scan the project.
5. After the analysis, the plugin shows a table with the detected smells for each test class and test case. The table can be sorted and filtered to easily spot test smells.
