FTP test step is normally used in combination with other test steps to create automated test cases. However, you can also use it to manually do FTP operations like uploading a file. (Actually, most types of test steps in API Test Base can be used to individually/manually invoke target API)
Actions available in the FTP test step: Put.
You can upload file from text or from file. The action uses passive mode to transfer file to the FTP server.
Target File Path
To create a remote file under the root path, enter ‘filename’. To create a remote file under specified path, enter ‘/path/to/the/filename’. Ensure the directory exists on the FTP server, otherwise you could see error returned from the FTP server.
