Testing load of a highchart utilizing python and selenium

To attend for a chart to be absolutely loaded earlier than persevering with along with your program, you need to use strategies like polling or ready for particular occasions. Here is an strategy utilizing JavaScript and the load occasion to attend for a chart to be absolutely loaded:

Add an Occasion Listener: You’ll be able to add an occasion listener to the chart factor to hear for the load occasion. This occasion is triggered when the chart is absolutely loaded and prepared for interplay.

Assuming you’ve gotten a chart factor with an id attribute like this:

You’ll be able to add an occasion listener in your JavaScript code as follows:

const chartElement = doc.getElementById('chart');

chartElement.addEventListener('load', perform() {
    // This code can be executed when the chart is absolutely loaded.
    // You'll be able to proceed along with your program right here.
});

Polling Method: If the chart would not have a built-in load occasion, you need to use a polling strategy to constantly verify whether or not the chart is loaded. You need to use setInterval to verify the chart’s standing at common intervals till it is absolutely loaded. Here is an instance:

perform checkChartLoaded() {
    const chartElement = doc.getElementById('chart');
    
    if (chartElement.full) {
        // The chart is absolutely loaded.
        // You'll be able to proceed along with your program right here.
    } else {
        // The chart shouldn't be absolutely loaded but.
        // You'll be able to set the polling interval to your required worth (e.g., 1000ms).
        setTimeout(checkChartLoaded, 1000);
    }
}

// Begin the polling course of
checkChartLoaded();

This code will hold checking whether or not the chart is absolutely loaded at 1-second intervals. As soon as it is absolutely loaded, it would proceed along with your program.
