If you want to test an SAPUI5 application in Business Application Studio (BAS) without using the UI5 tooling, you can follow these steps:
Open the terminal in BAS by selecting the menu option Terminal -> New Terminal.
Navigate to the root directory of your SAPUI5 application using the cd command.
Install the http-server package globally by running the following command:Copy codenpm install -g http-server This package will allow you to run a local HTTP server to serve your SAPUI5 application.
Start the HTTP server by running the following command:cssCopy codehttp-server -p 8080 -c-1This command will start the HTTP server on port 8080 and disable caching so that any changes you make to your application will be immediately visible when you refresh the page.
Open a web browser in BAS and navigate to http://localhost:8080/index.html, where index.html is the name of the main HTML file of your SAPUI5 application.
Your SAPUI5 application should now be loaded in the web browser and you can test it without using the UI5 tooling.
Note that this method assumes that you have already built your SAPUI5 application using the UI5 tooling and that the output files (e.g. index.html, Component-preload.js) are located in the root directory of your application.
