Pex: Automated Exploratory Testing for .NET
Pex: Automated Exploratory Testing for .NET
Pex (Program EXploration) is an intelligent assistant to the programmer. From a parameterized unit test, it automatically produces a traditional unit test suite with high code coverage. In addition, it suggests to the programmer how to fix the bugs.
Pex generates Unit Tests from hand-written Parameterized Unit Tests through Automated Exploratory Testing based on Dynamic Symbolic Execution.
• Unit Tests: parameterless methods that test a single unit of code
• Parameterized Unit Tests: same as above, but with parameters
• Automated Exploratory Testing: A tool-supported process of running, learning and testing code at the same time
• Dynamic Symbolic Execution: A combination of static analysis and runtime monitoring to compute test inputs.
