Shift-left testing gets all the attention, but it’s shift-right that reveals what truly works.

At @BlaBlaCar, Quality Assurance Manager @Rémy Gronencheld explains why testing in production is critical for real-world success:

1️⃣ Shift-left: Build with confidence but rely on assumptions.

2️⃣ Shift-right: Test against the unpredictable—low connections, real devices, and user behavior.

The reality? Combining both approaches lets teams take calculated risks without sacrificing quality.

Learn how BlaBlaCar balances shift-left and shift-right to deliver seamless user experiences on the latest episode of Test Case Scenario.
