Handling Slider on Web Testing with Drag and Drop can't get Width value from Excel? Running from Test Suites Problem

According to the MissingMethodException error message, the data type of “variable” in your statement (below) is a String rather than an Integer.

WebUI.dragAndDropByOffset(findTestObject('slider/slider_meninggal'), variable, 0)

Perhaps change your statement to:

WebUI.dragAndDropByOffset(findTestObject('slider/slider_meninggal'), Integer.parseInt(variable), 0)
