Functional Testcase Scenarios : 1) Check capture status with null stream. 2) Check capture status with hipStreamPerThread. 3) Functional : Create a stream, call api and check capture status is hipStreamCaptureStatusNone. 4) Functional : Start capturing a stream and check capture status returned as hipStreamCaptureStatusActive. 5) Functional : Stop capturing a stream and check status is returned as hipStreamCaptureStatusNone. 6) Functional : Use hipStreamPerThread, call api and check capture status is hipStreamCaptureStatusNone. 7) Functional : Start capturing using hipStreamPerThread and check capture status returned as hipStreamCaptureStatusActive. 8) Functional : Stop capturing using hipStreamPerThread and check status is returned as hipStreamCaptureStatusNone. 9) Functional : Create 2 streams s1 and s2. Start capturing s1. Record event e1 on s1 and wait for event e1 on s2. Queue some operations in s1 and s2. Invoke hipStreamIsCapturing on both s1 and s2. Verify that the capture info (status) of both s1 and s2 are identical. Record event e2 on s2 and wait for event e2 on s1. End the capture of stream s1. Invoke hipStreamIsCapturing on both streams.

In the thread get the capture info of s1 using hipStreamIsCapturing. Verify that it is in state hipStreamCaptureStatusActive in thread. Exit the thread and end the capture. 11)Functional : Create a stream with default flag (hipStreamDefault). Start capturing the stream. Invoke hipStreamIsCapturing() on the null stream. Verify hipErrorStreamCaptureImplicit is returned by hipStreamIsCapturing(). Verify capture status of created stream. Do some operatoins. End the capture on the created stream.
