Description

Typical failure look like:

[ERROR]   GatewayAppFuncTest.testMultiApps:338 1 expectation failed.
Expected status code <200> but was <404>. 

It happen in test which are running right after testDeploymentCleanup or 

testDefaultTopology. These tests restart the gateway service during the test run.

The subsequent test overwrite the topology file which are used by all tests but file access date granularity is 1 second (msec part is always 000, this is likley FS specific) therefore the topology is never redeployed.

 

Adding 

FileUtils.cleanDirectory(new File(config.getGatewayTopologyDir())); in between restarts seems to solve the issue.
