You can use following regex for it. Backreferencing will help you to combine whole file name:

/src\s*=\s*(?:"|')\/home\/ushus\/dev\/([^"']*)/ig

Example how to use it:

var regex = /src\s*=\s*(?:"|')\/home\/ushus\/dev\/([^"']*)/ig,
    content = 'src="/home/ushus/dev/testResults/1/431619110/screenshot_0.png"'
            +'\nsrc="/home/ushus/dev/testResults/1/431619110/screenshot_1.png"';
console.log(content.replace(regex, 'src="/dave/homedave/$1"'));
