Don't let this gap widen
Without mastering web automation and testing with Puppeteer, development teams lose an average of 50% of their time on repetitive and inefficient manual tests.
This generates deployment delays of up to 3 weeks per sprint and multiplies production error costs by 100, with 70% of critical bugs going unnoticed.
For the company, this is a strategic vulnerability that erodes competitiveness and exposes it to financial losses of 20 000 € per major incident.
For your career, staying manual means being outpaced by automated peers, with an imminent risk of professional stagnation.
