When I run my Espresso tests from Android Studio 2.2.1 using Test Lab for Android I get the following error message:
Exception while triggering a matrix execution. 429 Too Many Requests.
I managed to run several tests on remote devices, but then they start failing with this error message. Firebase console shows nothing.
What might be the issue?
This is the HTTP Status returned when a project that is on the Flame or Spark tier has used too much of its quota.
Projects on the Spark and Flame tier can send up to 10 virtual device tests and 5 physical device tests per day (with each day beginning at midnight PDT). In addition, there is a maximum of 4 tests per test matrix for projects on these plans.
