This blog post chronicles a troubleshooting journey while setting up JUnit tests for a Spring Boot backend application, highlighting common obstacles and their solutions.
The Initial Attempt and Quota Limits
We attempted to use an AI tool, often referred to internally as “Google Antigravity,” to help generate backend JUnit test cases for our spring-boot folder.
Unfortunately, during this initial phase, the free account limit for the AI tool was reached. This required a quick shift to an alternative account to continue the test generation process.
It’s a common hurdle in development: tools are essential, but resource constraints (like API limits or quotas) must be managed.
Encountering a Test Failure
After generating and incorporating the necessary test files (for example, for an Authentication Controller), the next step was to execute them using the Maven build tool.
We ran the specific test class using the command:
mvn test -Dtest=AuthControllerTest
This execution resulted in a test failure, as shown in the console output.
The error was likely related to the project’s dependencies, configuration, or, as we discovered, an incompatibility with the current Java Development Kit (JDK) environment path.
The JDK Compatibility Solution
To resolve the test failure, we consulted the error details and determined that the issue was related to JDK version compatibility. The project was built to run optimally on JDK 11, but the environment path was pointing to a different version or an incorrect location.
The critical fix involved updating the system or project configuration to explicitly use the correct JDK 11 installation path. The path we configured was:
C:\Program Files\Java\jdk-11.0.10\bin
By correctly configuring the environment to use the JDK 11 binaries, we ensured that all dependencies and compilation steps aligned with the required version.
Successful Test Execution
With the JDK path corrected, we executed the full suite of backend tests using the standard Maven command:
mvn test
The test run completed successfully, confirming that the JUnit test cases were correctly implemented and executed against the Spring Boot application.
This journey highlights the importance of checking JDK and environment compatibility when troubleshooting backend test failures. A simple path change was the final step to a successful test suite!
