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 should utilize strategies like polling or ready for particular occasions. This is an strategy utilizing JavaScript and the load occasion to attend for a chart to be absolutely loaded:

Add an Occasion Listener: You may add an occasion listener to the chart aspect 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 aspect with an id attribute like this:

You may add an occasion listener in your JavaScript code as follows:

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

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

Polling Strategy: If the chart does not have a built-in load occasion, you should utilize a polling strategy to repeatedly verify whether or not the chart is loaded. You should use setInterval to verify the chart’s standing at common intervals till it is absolutely loaded. This is an instance:

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

// Begin the polling course of
checkChartLoaded();

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