How to perform file upload operation in your application?

You can use FILE_UPLOAD command as follows:

• Hover over Repository and File Uploads from the menu
• Click Add to upload a file that you want to use in your test case 
• Alternatively, you can use a file which was uploaded externally to a storage service, such as Dropbox, but make sure that the link directly downloads a file and not opens in a preview mode.
• In your test case, use FILE_UPLOAD command in a step
• Two drop-downs are presented
• Select the file upload locator for your application from the list of locators available in the first drop-down. Alternatively, you can use Inline with this XPath: //input[@type='file']
• Select the file you uploaded in the above bullet from the second drop-down or click URL and enter the URL of the file.

• Save your test case and run it to confirm that the upload is successful.

NOTE: The XPath for the locator must reference an input tag with type = "file". For example

//input[@type='file']
