--------------------------------------------
Summary: camel-core: review File tests for incorrectly shared
resources
Key: CAMEL-20686
URL: https://issues.apache.org/jira/browse/CAMEL-20686
Project: Camel
Issue Type: Task
Components: camel-core
Affects Versions: 4.6.0
Reporter: Otavio Rodolfo Piske
Fix For: 4.x
We have lots of file tests in core that run in parallel and try to write to the
same file. This leads to a lot of flakiness in file tests.
Look for tests doing things like {{testFile("output.txt")}} or
{{testFile("input.txt")}} or other similar repetitive names (i.e.: {{{}foo{}}},
{{{}bar{}}}, etc) should be considered suspicious and need careful review.
The tests should be adjusted to one of the following (in order of preference):
* Use separate resources for each test (i.e: "{{{}input." +
TestClass.class.getSimpleName() + ".txt"{}}})
* Use JUnit's 5 temporary file provider
* Use resource locks via JUnit's {{@ResourceLock}} annotation.
* Or Isolated if safe to do so
