This tool paper presents an embodiment of TestEra -a framework developed in previous work for specification-based testing of Java programs. To test a Java method, TestEra uses the method's pre-condition specification to generate test inputs and the post-condition to check correctness of outputs. TestEra supports specifications written in Alloy -a first-order, declarative language based on relations -and uses the SAT-based back-end of the Alloy tool-set for systematic generation of test suites.

Each test case is a JUnit test method, which performs three key steps: (1) initialization of pre-state, i.e., creation of inputs to the method under test; (2) invocation of the method; and (3) checking the correctness of post-state, i.e., checking the method output. The tool supports visualization of inputs and outputs as object graphs for graphical illustration of method behavior. TestEra is available for download to be used as a library or as an Eclipse plug-in.
