Techniques for serverless performance testing of applications are provided. A user can indicate an application to test within a serverless computing framework. The user can specify parameters for testing the application. A performance test execution file can be generated based on the indicated application and the specified testing parameters. Serverless functions for implementing the testing of the application can be generated based on the performance test execution file. The serverless functions can be executed to implement the testing of the application code on a cloud-based computing resource. Test outputs can be generated and stored for review and analysis in real-time during the testing and after the testing is concluded.
