Impairment in an application test execution

A non-transitory computer-readable medium, comprising instructions that, when executed, cause a test device to:

• access a test profile to determine whether a test impairment is to be introduced artificially into a test execution of a program in a distributed test environment;
• responsive to the test profile directing introduction of the test impairment, measure an actual impairment in communication of data in the distributed test environment and subtract the actual impairment from the test impairment;
• separate from the actual impairment, introduce an artificial impairment into the test execution of the program in the distributed test environment, the artificial impairment being the actual impairment minus subtracted from the test impairment;
• and
• when performing the test execution of the program in the distributed test environment, simulate a real operating environment using a simulated impairment that includes the introduced artificial impairment added to the actual impairment in the distributed test environment.

A system comprising:

• a processor;
• a non-transitory storage medium storing instructions executable on the processor to:
• measure an actual impairment of packets communicated in a distributed test environment;
• and
• during a test execution of a program in the distributed test environment:
• compute an artificial impairment based on subtracting the actual impairment from a specified test impairment,
• selectively introduce the artificial impairment into communication of packets in the distributed test environment, and
• simulate a real operating environment using an impairment that includes the introduced artificial impairment added to the actual impairment in the distributed test environment.
