Opened on behalf of @JiayiLi1

The test System.Data.SqlClient.Tests.SqlConnectionBasicTests/IntegratedAuthConnectionTest has failed.

System.Data.SqlClient.SqlException : Connection Timeout Expired. The timeout period elapsed during the post-login phase. The connection could have timed out while waiting for server to complete the login process and respond; Or it could have timed out while attempting to create multiple active connections. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=1; handshake=17; [Login] initialization=0; authentication=1; [Post-Login] complete=3998; \r
---- System.ComponentModel.Win32Exception : The wait operation timed out

I don't understand why this test is failing in the coreclr pipeline!!
Is there anything different about the way the tests are built in CoreCLR pipeline vs corefx ?

Is there anything different about the way the tests are built in CoreCLR pipeline vs corefx ?

I am not sure. Maybe these guys can provide some insight: @jkotas, @stephentoub, @AndyAyersMS

[jkotas]

There are environment differences. The main ones I can think of:

• corefx runs the tests on release build of the runtime but coreclr CI runs them on checked build of the runtime
• corefx runs the tests in helix but coreclr CI runs them on Jenkins machines
