Exception
Condition
Browser was still open after several retries to close it.

EnvironmentReady

This method checks that the desktop of the environment is completely loaded and checks the CPU load of the SUT from the cmd window to ensure the system is responsive (CPU load below 40%). If an installer testcase is used, this should be called from installer Precondition step, otherwise from test case Precondition step.

Syntax:

public bool EnvironmentReady(
bool checkSystemResponsive = true
)

Parameters:

Parameter
Description
[checkSystemResponsive]
Type: Boolean If this is false, the responsivenes check is disabled. True by default.

Return Value:

True if the system is responsive. Otherwise methods throws a SUTNotReadyException that will trigger a VM Redeployment for cloud VMs.

Exceptions:

Exception
Condition
If the system is not responsive, a SUTNotReadyException is trown that will trigger a VM Redeployment for cloud VMs.

GetCpuLoadPercentage

Determines the current CPU load percentage on the SUT by running the wmic cpu get loadpercentage.

Syntax:

public int GetCpuLoadPercentage()

Return Value:

An integer value between 0 and 100 indicating the CPU load percentage on the SUT.

Exceptions:

Exception
Condition
Either the command to get the cpu load did not complete or the cpu load percentage could not be parsed from the response of the command.

GetComputerName

Gets the computer name of the SUT with the hostname command.

Syntax:

public string GetComputerName()

Return Value:

The computer name as a string.

Exceptions:

Exception

SetUpRemoteDirectory Method

Overload List

Name
Description
Mounts the remote directory that is provided by the execution host. If assigned drive is already in use, it is disconnected first. Uses default drive letter R.
Mounts the remote directory that is provided by the execution host to the specified drive. If assigned drive is already in use, it is disconnected first.

SetUpRemoteDirectory()

Mounts the remote directory that is provided by the execution host. If assigned drive is already in use, it is disconnected first. Uses default drive letter R.

Syntax:

public void SetUpRemoteDirectory( )

Exceptions:

Exception
Condition
Either the previous mapping could not be removed or the current remote directory could not be mapped.

SetUpRemoteDirectory(Char)

Mounts the remote directory that is provided by the execution host to the specified drive and updates ArtifactsDirectory, SupportingFilesDirectory etc accordingly. If assigned drive is already in use, it is disconnected. Note: The Drive Letter is not persisted from Installer to TestCase, so if you SetupRemoteDirectory in Installer, the TestCase will again default to 'R' for ArtifactsDirectory etc.

Syntax:

public void SetUpRemoteDirectory(
char driveLetter
)

Parameters:

Parameter
Description
driveLetter
Type: Char
The drive letter to which the remote directory shall be mapped to.
