As described in the lambda configuration section, running XSpec test suites can be a memory and time intensive process and parameters for memory allocation and timeout need to be adjusted according to the number and type of XSpec tests.

AWS Lambda enables to run a function for up to 15 minutes, after which the function will automatically timeout. Therefore the XSpec test suite needs to run within this time constraint. This limitation is useful as it helps keeping the test suite manageable and its execution fast enough to provide feedback to developers within a short time frame. As the test suite becomes more complex and more tests are added, it is recommended to break it down into different groups and assign a lambda function for each group of XSpec tests. This offers the advantage of running multiple lambda functions in parallel and keeps the total execution within the 15 minute time constraint.
