Symbolic executionSymbolic executionSymflower relies on symbolic execution to generate high-coverage JUnit tests for your Java, Spring, or Spring Boot applications.
Our IDE plugin symbolically executes your code to identify the input values that trigger the execution of all possible paths in your code resulting in high-coverage tests for your source code.
Symflower is available in the IDE of your choice, your favorite terminal and as a CI/CD integration.
Symflower’s test suites contain essential tests that cover all possible unique paths of your code. Test candidates are computed instead of being randomly chosen, resulting in mathematical precision and the highest test coverage possible.
Unit tests generated by Symflower are easy to read and understand. Generated test templates follow mainstream conventions, test inputs are optimized for reading, and mocks are used automatically for both Java and Spring Boot applications.
Not restricted to primitive data types and simple source code. Symflower can handle and analyze concepts such as complex data types, interfaces and object orientation.
No redundant test cases. Each generated test case adds value by executing a new behavior of a function.
Generate all the boilerplate code for unit testing, and focus on your actual test candidates.
Generated tests reveal edge cases for you to debug, and provide instant reproducers for your source code.
Symflower works out-of-the-box. Install the plugin in your IDE or download the CLI version and get started.
Forget having to figure out how to design inputs to test a certain part of your source code. Generate JUnit tests rapidly and with mathematical precision.
Automatically generate mocks for interfaces with their behavioral checks, and handle all unanticipated possibilities. Mocking is supported for both Java and Spring Boot applications.
Symflower runs on your machine and does not send your code to any servers.
Understand symbolic execution, the solution that helps Symflower automatically create unit test cases with high coverage.
