Click the (rerun) link in the command window to rerun the failed test. You cannot rerun

failed tests if the variable that stores the test results is overwritten. If the link is no longer

in the Command Window, you can type results at the prompt to view it.

TestResult with properties:

Name: 'exampleTest/testSquare'

Passed: 1

Failed: 0

Incomplete: 0

Duration: 0.0034

Details: [1×1 struct]

Totals:

1 Passed, 0 Failed, 0 Incomplete.

MATLAB stores the TestResult array associated with tests that you rerun in the ans

variable. results is a 1x2 array that contains all the tests in exampleTest.m, and ans

is a 1x1 array that contains the rerun results from the one failed test.

Name Size Bytes Class Attributes

ans 1x1 664 matlab.unittest.TestResult

results 1x2 1344 matlab.unittest.TestResult

suite 1x2 96 matlab.unittest.Test

To programmatically rerun failed tests, use the Failed property on the TestResult

object to create and run a filtered test suite.
