Unit's parallel testing PHP class library

add(new ParaTestCommand(new PHPUnit())); return parent::doRun($input, $output); }

Parallel testing technology is a method and technology formed by introducing parallel technology into the testing field. It is an advanced testing method and technology that can better complete the task of testing multiple objects under test (UUTs) at the same time. Parallel testing is based on the concept of parallelism. The core of parallel testing is that multiple objects under test can be tested at the same time. Parallel testing mainly achieves parallel testing by switching between different objects under test. The testing process of each tested object is independent and parallel. The test of one tested object does not have to wait until the test of another tested object is completed before it can be carried out. However, the internal testing process of each tested object is still tested in sequence. Therefore, this parallel testing method has limited improvement in the test performance and instrument utilization of the test system, and there is still a lot of room for improvement
