Sequencing

Sequencing is a set of testing steps for verifying that sequences of device behavior are correct.

Contained Test Suite

bin/test_sequencer $PROJECT_ID

This:

• Sets up /tmp/validator_config.json
• Sets up /tmp/pubber_config.json
• Automatically runs pubber instance for bin/sequencer test run.
• Runs complete battery of sequence tests by default, or incremental tests from command line.
• Updates sequence cache in validator/sequences/ to optimize incremental runs.
• Compares output in /tmp/sequencer.out against etc/sequencer.out

Sequencer Testing

In two separate terminals:

• pubber/bin/run /tmp/pubber_config
• bin/sequencer $PROJECT_ID

This:

• Runs pubber with the configuration setup by bin/test_sequencer
• Pubber does not normally need to be restarted with each run.
• Runs the sequencer, which can likewise be limited to individual tests.
• Doesn’t check results or do any other wrapped-for-testing processing.

Individual Tests

At its heart, sequence tests are JUnit @Test classes that can be run individually within an IDE. This is useful for development because it enables breakpoints and all that jazz. Still need to run the two parts, with several different options:

For Pubber:

• bin/pubber with appropriate arguments.
• pubber/bin/run /tmp/pubber_config as per above.
• Run pubber in the IDE if you want to breakpoint, etc…

For sequence testing:

• bin/sequencer as per above.
• Direct in IDE as a JUnit @Test. Either at the class level or method level.
