When running the TestDisconnected function of the otlp_integration_test.go file appears error

[hanyuancheung]

Description

When running make test according to the CONTRIBUTING.md, I found something wrong with TestDisconnected function. The error message is that as newGRPCExporter() was called and then tracesDriver start a connection, it occurs WaitForStateChange error. But after I comment out the otlpgrpc.WithDialOption() used in newGRPCExporter function as a param, the test case could access normally. Please make sure if the otlpgrpc.WithDialOption() configuration should be there in this test function thx.

Environment

• OS: MacOS X 10.15.7
• Architecture: amd64
• Go Version: Both 1.16.3 & 1.15.6
• opentelemetry-go version: v0.19.0

Steps To Reproduce

1. Clone the latest repo as the source code with https://github.com/open-telemetry/opentelemetry-go
2. Run make test as CONTRIBUTING.md going
3. See error with panic: test timed out, which is caused by TestDisconnected function in otlp_integration_test.go file

Expected behavior

It could be helpful if all of the test case can run successfully so that other guys could get started faster to contribute. Great honor~!

@zhyChesterCheung Test works perfectly fine for mentioned environment specification.

The old OTLP exporter (and thus this test) was removed in #1990. Feel free to create a new issue if this error is reproducible with the new exporter implementation.
