## ${docGenDescription}

## Prerequisites

A SAP Cloud Platform ABAP Environment system is available.
On this system, a [Communication User](https://help.sap.com/viewer/65de2977205c403bbc107264b8eccf4b/Cloud/en-US/0377adea0401467f939827242c1f4014.html), a [Communication System](https://help.sap.com/viewer/65de2977205c403bbc107264b8eccf4b/Cloud/en-US/1bfe32ae08074b7186e375ab425fb114.html) and a [Communication Arrangement](https://help.sap.com/viewer/65de2977205c403bbc107264b8eccf4b/Cloud/en-US/a0771f6765f54e1c8193ad8582a32edb.html) is setup for the Communication Scenario "SAP Cloud Platform ABAP Environment - Software Component Test Integration (SAP_COM_0510)". This can be done manually through the respective applications on the SAP Cloud Platform ABAP Environment System or through creating a service key for the system on cloud foundry with the parameters {"scenario_id": "SAP_COM_0510", "type": "basic"}. In a pipeline, you can do this with the step [cloudFoundryCreateServiceKey](https://sap.github.io/jenkins-library/steps/cloudFoundryCreateServiceKey/). In addition, the software component should be cloned into the system instance. You can do this with the step [abapEnvironmentPullGitRepo](https://sap.github.io/jenkins-library/steps/abapEnvironmentPullGitRepo/).

## Example: Configuration in the config.yml

The recommended way to configure your pipeline is via the config.yml file. In this case, calling the step in the Jenkinsfile is reduced to one line:

```groovy
abapEnvironmentCheckoutBranch script: this
```

If you want to provide the host and credentials of the Communication Arrangement directly, the configuration could look as follows:

```yaml

steps:
  abapEnvironmentCheckoutBranch:
    repositoryName: '/DMO/GIT_REPOSITORY'
    branchName: 'my-demo-branch'
    abapCredentialsId: 'abapCredentialsId'
    host: '1234-abcd-5678-efgh-ijk.abap.eu10.hana.ondemand.com'
```
Please note that the branchName parameter specifies the target branch you want to switch on. Also keep in mind that the repositoryName parameter must define a single repository.

If you want to read the host and credentials from the cloud foundry service key of the respective instance, the configuration could look as follows:

```yaml
steps:
  abapEnvironmentCheckoutBranch:
    repositoryName: '/DMO/GIT_REPOSITORY'
    branchName: 'my-demo-branch'
    cfCredentialsId: 'cfCredentialsId'
    cfApiEndpoint: 'https://test.server.com'
    cfOrg: 'cfOrg'
    cfSpace: 'cfSpace'
    cfServiceInstance: 'cfServiceInstance'
    cfServiceKeyName: 'cfServiceKeyName'
```

## Example: Configuration in the Jenkinsfile

It is also possible to call the steps - including all parameters - directly in the Jenkinsfile.
In the first example, the host and the credentialsId of the Communication Arrangement are directly provided.

```groovy
abapEnvironmentCheckoutBranach (
  script: this,
  repositoryName: '/DMO/GIT_REPOSITORY',
  branchName: 'my-demo-branch',
  abapCredentialsId: 'abapCredentialsId',
  host: '1234-abcd-5678-efgh-ijk.abap.eu10.hana.ondemand.com'
)
```

In the second example, the host and credentialsId will be read from the provided cloud foundry service key of the specified service instance.

```groovy
abapEnvironmentCheckoutBranch (
  script: this,
  repositoryName: '/DMO/GIT_REPOSITORY',
  branchName: 'my-demo-branch'
  abapCredentialsId: 'cfCredentialsId',
  cfApiEndpoint: 'https://test.server.com',
  cfOrg: 'cfOrg',
  cfSpace: 'cfSpace',
  cfServiceInstance: 'cfServiceInstance',
  cfServiceKeyName: 'cfServiceKeyName'
)
```
