For development purpose, you can specifiy which tests to run by using:
```
# Run every tests in the MyTest suite
TESTFLAGS="-check.f MyTestSuite" make test-integration
# Run the test "MyTest" in the MyTest suite
TESTFLAGS="-check.f MyTestSuite.MyTest" make test-integration
# Run every tests starting with "My", in the MyTest suite
TESTFLAGS="-check.f MyTestSuite.My" make test-integration
# Run every tests ending with "Test", in the MyTest suite
TESTFLAGS="-check.f MyTestSuite.*Test" make test-integration

## Constraints
In a micro-service architecture, with a central service discovery, setting constraints limits Træfɪk scope to a smaller number of routes.
Træfɪk filters services according to service attributes/tags set in your configuration backends.
Supported backends:
- Consul Catalog
Supported filters:
- ```tag```
```
