2023.10

2023-10-09T15:53:13Z

UnitTestBot can now generate tests for Spring applications.

It automatically detects if you use the Spring framework and provides you with necessary options right in the dialog window.
You can choose from the three approaches to Spring test generation:
- standard unit tests that mock environmental interactions,
- Spring-specific unit tests that use information about the Spring application context,
- and integration tests that validate interactions between Spring components.

Find more improvements and bug fixes:

Support for IntelliJ IDEA 2023.2
Taint analysis feature (experimental)
Improved mocking in symbolic execution engine
Enhanced fuzzing mechanism: improved domain-specific API and mutation processes; support for generic fields and resolving generic parameter types; single branch detection, and ability to use all public methods of a class under test
Improved UIs for standard Java, Spring, and Python test generation
Fixed bugs for symbolic execution engine, fuzzing, code generation and instrumented process, summaries, SARIF reports, and more
Multiple improvements for Python support related to rendering constructors; mastering exceptions, timed out tests, and regular expressions; fixes for coverage and shutting down behavior
Enhanced Go test generation: support for maps and user-defined types

Full Changelog: 2022.5-alpha...2022.7-beta

2022.5-alpha

2022-05-28T22:39:20Z

This is the very first alpha version of UTBotJava, automated test generator for Java. We tested it on Win64 and Linux64 and it currently doesn't work for MacOS (will be fixed soon).

Give a try to our IntelliJ IDEA plugin (click to download). After plugin is installed you can run UTBot with few clicks.

In this version:

Generation of regression/error tests with a single action Generate tests with UtBot for folder, class or method.
Statement and branch coverage maximization
Tests in Error suite are generated for all implicitly thrown RuntimeException (e.g. NullPointerException, ArrayIndexOutOfBoundsException, etc.); these tests are failed by default (customizable in "File -> Settings -> UTBot")
Tests that runs too long are put into Timeout suite
Test that fails JVM are put into Crash suite
Minimize number of generated test, not loosing coverage and detected errors
Human-readable names and comments for generated tests
