This may sound rather crazy, but I cannot find a solution to automate taking screenshots on a cordova application.
I know I can take and save a screenshot of the emulator using
adb shell /system/bin/screencap -p /sdcard/screenshot.png
adb pull /sdcard/screenshot.png screenshot.png
in the terminal, my crazy question is. Can I trigger these commands from a nodeJS automation script? or is this too far fetched and a terrible idea?
Simplest way to execute terminal commands from node.js would be to use child_process.exec
const exec = require('child_process').exec;
exec('adb shell /system/bin/screencap -p /sdcard/screenshot.png', (error, stdout, stderr) => {
if (error) {
console.error(`exec error: ${error}`);
return;
}
console.log(`stdout: ${stdout}`);
console.log(`stderr: ${stderr}`);
});
The built-in child_process module in node.js provides many functions such child_process.spawn, child_process.exec, child_process.execFile which can be used to execute terminal commands or other script files (.sh, .bat).
