From f873d801ddd1e040e27e9aed80c63e822a2321d7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Niklas=20S=C3=B6derlund?= Date: Wed, 6 Mar 2019 01:35:00 +0100 Subject: test: camera: Add capture test MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Correctly configure the camera using the default configuration and run a capture session for 100 milliseconds, which is plenty of time, in tests over 600 requests completed using the vimc pipeline. The test passes if at least the number of buffers used in the capture times two number of requests completes to prove we cycle through all buffers.
