Any way to integrate Robot Framework Selenium Tests with Google Lighthouse?

[Chinmaya Karve]

Hi Community,

Is there any way to integrate Google Lighthouse with RF driven UI tests? The use case is, when a new browser instance is initiated through RF test, I want to initiate Lighthouse analysis of the opened page and stop monitoring when the test is over.

Has this been tried before? Does this make sense> Any way to achieve this?

Thank much!

1. Install the Lighthouse Node.js module using the following command:

   Copy code
   npm install -g lighthouse
   

2. Create a new RF test case and add the following steps:

   javascriptCopy code
   Open Browser    https://www.example.com    chrome
   Execute JavaScript    lighthouse('https://www.example.com', {output: 'json', logLevel: 'info'}).then(results => console.log(JSON.stringify(results)))
   Close Browser

1. In the above code, we are using the "Execute JavaScript" keyword to execute the Lighthouse command to analyze the performance of the web page. The output of the Lighthouse command is in JSON format and is printed to the console.

2. You can also use the RF "Run Keyword If" keyword to run the Lighthouse command only when the test is initiated and stop monitoring when the test is over. For example:

bashCopy code
${browser}    Open Browser    https://www.example.com    chrome
${lighthouse_command}    Set Variable If    '${TEST NAME}' == 'My Test Case'    lighthouse('https://www.example.com', {output: 'json', logLevel: 'info'}).then(results => console.log(JSON.stringify(results)))    ${EMPTY}
${lighthouse_output}    Execute JavaScript    ${lighthouse_command}
Log    ${lighthouse_output}
Close Browser

In the above code, we are using the "Set Variable If" keyword to set the Lighthouse command in a variable only when the test case name matches "My Test Case". The Lighthouse command is executed using the "Execute JavaScript" keyword and the output is printed to the log file.
