Rather than tediously writing unit tests manually, tools can be used to generate them
automatically-sometimes even resulting in higher code coverage than manual testing. But …

Regression testing is important but can be time-intensive. One approach to speed it up is
regression test selection (RTS), which runs only a subset of tests. RTS was proposed over …

Software bugs can cause significant financial loss and even the loss of human lives. To
reduce such loss, developers devote substantial efforts to fixing bugs, which generally …

Testing aims at detecting (regression) bugs in production code. However, testing code is just
as likely to contain bugs as the code it tests. Buggy test cases can silently miss bugs in the …

Event-driven applications, such as, mobile apps, are difficult to test thoroughly. The
application programmers often put significant effort into writing end-to-end test suites. Even …

Writing reliable test suites for large object-oriented systems is complex and time consuming.
One common cause of unreliable test suites are test dependencies that can cause tests to …

Slow builds remain a plague for software developers. The frequency with which code can be
built (compiled, tested and packaged) directly impacts the productivity of developers: longer …

System testing and invariant detection is usually conducted from the user interface
perspective when the goal is to evaluate the behavior of an application as a whole. A large …

In a test suite, all the test cases should be independent: no test should affect any other test's
result, and running the tests in any order should produce the same test results. The …

Tests are increasingly specified as programs. Expressing tests as code is advantageous in
that developers are comfortable writing and running code, and tests can be automated and …
