Maximally parallel test script execution

A non-transitory computer-readable data storage medium storing program code executable by a processor to perform processing comprising:

• causing sequential execution of a plurality of test commands of a test script, the test commands sequentially ordered within the test script;
• monitoring a parameter as the test commands are sequentially executed;
• and
• dividing the test commands over a plurality of tests of the test script in correspondence with changes in the parameter greater than a threshold.

A system comprising:

• a plurality of testing devices of different testing device types;
• a testing manager device to, for each unique path of a maximally parallel subset of unique paths that cover all tests into which a test script has been divided:
• attempt execution of the tests covered by the unique path on the testing devices of the different testing device types;
• mark, as an impermissible testing device type for the unique path, each testing device type of the testing devices on which the execution of any test covered by the unique path failed;
• and
• assign the tests covered by the unique path to the testing devices other than the testing devices of any impermissible testing device type for the unique path.
