> h1. Prepare to build Flink binaries and test jobs
>
> h3. 1. Environment requirements:
> Standard JDK and Maven setups for building Flink from source will suffice.
> h3.
> 2. Build flink binary file
> {code:java}
> # cd into you target directory
> git clone https://github.com/apache/flink # $repo_path, the placeholder name
> will be used later.
> cd flink
> git checkout ${target_tag or target_branch}
> mvn clean package -DskipTests -T 4C {code}
> h3.
> 3. Build an example job
> {code:java}
> mvn archetype:generate \
> -DarchetypeGroupId=org.apache.flink \
> -DarchetypeArtifactId=flink-walkthrough-datastream-java \
> -DarchetypeVersion=2.2.0 \
> -DgroupId=frauddetection \
> -DartifactId=frauddetection \
> -Dversion=0.1 \
> -Dpackage=frauddetection \
> -DinteractiveMode=false
> cd frauddetection
> mvn clean package -DskipTests {code}
> h1. Testing cases for streaming jobs
> h2. For disabled adaptive scheduler and disabled max rescale history
> 1. run shell command:
>
> {code:java}
> cd $repo_path/build-target
> ./bin/start-cluster.sh {code}
> 2. Visit http://localhost:8081/
> 3. Use flink WEB UI to submit the frauddetection jar as a job.
> 4. Check if the UI shown logic is correct
> The testing case will be expected if the there isn't Rescale tab page in UI
> like follows,
> If not , this test would be tagged failed.
