Description

The geko test command now reports real-time progress while tests are running, showing how many tests have been executed and how many have failed, plus a summary line when the run completes.

Until now, running tests produced no feedback after the build finished, so it was impossible to tell whether a test run was progressing, how many tests had executed, or whether any had failed until the process ended.

Motivation and Context

Test runs could run for a long time with no feedback, which made it hard to tell whether things were progressing, how many tests had executed, and whether failures had already occurred. This change parses xcodebuild's test output directly into structured lifecycle events and surfaces an aggregated, real-time progress summary so users get clear feedback on test execution without waiting for the run to finish.
