Testing
Note: Info here is for pre-v1.0.0 and will need to be updated
In the metadata-etl model for local testing, it might have too many steps to set up a database and make all the configurations. So we provide a way to read all configurations from a local file. There is already a template of the configuration file in local_test.properties. You can find detail of properties in each job type's wiki.
If you are running the test through IDE, make sure the local_test.properties file location is correct (default at ~/.wherehows/local_test.properties)
Also, each ETL job can be run as a standalone job. The command line format is :
java -Dconfig=/path/to/config/file -cp "all the classpaths" metadata.etl.Launcher
| parameter | meaning |
|---|---|
| -Dconfig | Config file location is the configs that you want to use to test the program. You can also sepcify each properties by using '-D', but it's more tedious |
| -cp | Class path is all jar files location after you build the project. Normally after gradle build, the folder backend-service/lib contain all jar files |
You can also add any JVM parameters such as -Xms512M -Xmx1024M for your testing purpose.
Example :
java -Dconfig=/path/to/config/file -cp "lib/*" metadata.etl.Launcher
