SAP Business Application Studio and SAP Build Code do not come with Chrome pre-installed, and it cannot be installed via the CLI. However, you can use Firefox, which will be installed once you add the "Headless Testing Framework." as an additional SAP Extension.

To do this, go to SAP Business Application dev space management. First, stop your development space and enter edit mode. You should see a screen similar to what is shown below. Select "Headless Testing Framework" and Save Changes. 

Now you need to configure WDI5 as per doc https://ui5-community.github.io/wdi5/#/usage?id=using-bas-with-wdi5

by the way, now you can also run UI5 Test Runner, too, to test:

• Clone https://github.com/ArnaudBuchholz/training-ui5con18-opa
• cd training-ui5con18-opa and run npm install
• Install ui5-test-runner globally with npm install ui5-test-runner --global

Now you need to select 'Automation Library' which supports Firefox, e.g.

• using selenium-webdriver run following in your terminal ui5-test-runner --browser $/selenium-webdriver.js -- --browser firefox
• using webdriver.io run following in your terminalui5-test-runner --browser $/webdriverio.js -- --browser firefox

Hi,

The Headless Testing Framework extension installs the Firefox browser which allows you to use the wdi5 capabilities when working in SAP Business Application Studio.. Please check here https://ui5-community.github.io/wdi5/#/usage?id=using-bas-with-wdi5

KR,
