--------------------------------------
Hi [~martijnvisser] , but without the `<type>test-jar</type>` in your
depenency, one cannot use the TestHarness, because they live in the test
package in code here:
[https://github.com/apache/flink/blob/4a742c86a917af432c0a6ec433acf18c176faf1f/flink-streaming-java/src/test/java/org/apache/flink/streaming/util/KeyedTwoInputStreamOperatorTestHarness.java#L34]
> Flink Testing doc missing key information about dependency
> ----------------------------------------------------------
>
> Key: FLINK-32323
> URL: https://issues.apache.org/jira/browse/FLINK-32323
> Project: Flink
> Issue Type: Improvement
> Components: Documentation
> Reporter: Lim Qing Wei
> Priority: Major
>
> On this doc:
> [https://nightlies.apache.org/flink/flink-docs-master/docs/dev/datastream/testing/]
>
> It links to this doc
> [https://nightlies.apache.org/flink/flink-docs-master/docs/dev/configuration/testing/]
> for project configuration. But it does not mention to use the TestHarness
> from Flink, we also need to add the following dependency:
>
> {noformat}
> <dependency>
> <groupId>org.apache.flink</groupId>
> <artifactId>flink-streaming-java</artifactId>
> <version>${flink.version}</version>
> <type>test-jar</type>
> <scope>test</scope>
> </dependency>{noformat}
