How to Upload and Download a file in Robot Framework

In this article, we will discuss in detail how we can upload and download a file in Robot Framework. We would be using three libraries for our tests:

1. SeleniumLibrary – We need to install this and import. To install we have to use – pip3 install robotframework-seleniumlibrary.
2. BuiltIn Library – This comes inbuilt with robot framework, so no need to install anything or import anything.
3. OperatingSystem – This also comes inbuilt with robot framework, so no need to install anything, but we need to import this.

To further deep-dive let’s automate two test cases.

Test-Case 1
1. Upload an image file.
2. Verify that the file is uploaded successfully.

Test-Case 2
1. Download an image file to our desired folder.
2. Verify that the file is downloaded successfully.
 

> Verify File Upload – Test Case name.

> [documentation] This test case verifies that a user can successfully upload a file – This gives us more details about the test case.

> [tags] Regression – This test case is tagged as ‘Regression’.

> Open Browser https://the-internet.herokuapp.com/upload Chrome – Opens the given url in chrome browser.

> Wait Until Element Is Visible id:file-submit timeout=5 – This will wait for a maximum of 5 seconds for the element to be visible on the web page.

> Choose File id:file-upload /Users/alapan/PycharmProjects/Robot-Framework/Resources/Upload/sunset.jpg – Choose File inputs the file path into the file input field locator. Here we are providing the absolute path of the image.

> Clicks Element id:file-submit – Clicks the upload button.

> Element Text Should Be tag:h3 File Uploaded! timeout=5 – Validates the presence of text ‘File Uploaded!’ on the webpage.

> Element Text Should Be id:uploaded-files sunset.jpg timeout=5 – Once the file is successfully uploaded, the file name ‘sunset.jpg’ is displayed on the webpage. Here we are validating the same.

> Close Browser – Finally we are closing the browser and ending the test.
 

> Verify File Download – Test case name.

> [documentation] This test case verifies that a user can successfully download a file – This gives us more details about the test case.

> [tags] Regression – Test case is tagged as ‘Regression’.

> ${chrome options}= Evaluate sys.modules[‘selenium.webdriver’].ChromeOptions() sys, selenium.webdriver – This Evaluates the given expression in Python and returns the result. This basically enables us to use capabilities and chromeoptions for chrome browser.

> ${prefs} Create Dictionary
… download.default_directory=/Users/alapan/PycharmProjects/Robot-Framework/Resources/Download – This is creating a dictionary with the key ‘download.default_directory’ and the value as the absolute path of the download folder ‘/Users/alapan/PycharmProjects/Robot-Framework/Resources/Download’.

> Call Method ${chrome options} add_experimental_option prefs ${prefs} – Call Method calls the named method of the given object with the provided arguments. The possible return value from the method is returned and can be assigned to a variable.

> Create Webdriver Chrome chrome_options=${chrome options} – Create Webdriver creates an instance of Selenium WebDriver. Like Open Browser, but allows passing arguments to the created WebDriver instance directly. Here we are passing ${prefs} which contains our Download folder path.

> Goto https://the-internet.herokuapp.com/download – Opens the url in the chrome browser.

> Click Link css:[href=”download/sunset.jpg”] – Clicks the ‘sunset.jpg’ link from the list of links.

> Sleep 5s – Pauses the test for 5 seconds to make sure that the file is downloaded successfully.

> ${files} List Files In Directory /Users/alapan/PycharmProjects/Robot-Framework/Resources/Download – As the name suggests, List Files In Directory gets the number of files in the current directory.

> Length Should Be ${files} 1 – Now if the download is successful the number of files should be 1. Here we are validating this.

> Close Browser – Finally we are closing the browser and ending the test.
 
After execution, we should get a ‘PASS’.

After download, the file should be reflected under the ‘Download’ folder –
