## ESX-LISA is an automation testing framework based on github.com/LIS/lis-test
## project. In order to support ESX, ESX-LISA uses PowerCLI to automate all
## aspects of vSphere maagement, including network, storage, VM, guest OS and
## more. This framework automates the tasks required to test the
## Redhat Enterprise Linux Server on WMware ESX Server.
########################################################################################

.Synopsis
Perform tests on a VM as defined in a .xml file
.Description
This powershell script automates the tasks required to test
the Redhat Enterprise Linux Server on WMware Server.
This script is the entry script into the automation. The basics
behavior of the automation is:
Start a VM
Push files to a VM
Start a script executing on a VM
Collect files from a VM
Shutdown a VM
Other required powershell scripts includes:
stateEngine.ps1
Provides the functions that drive the VMs through
various states that result in a test case being
run on a VM.
utilFunctions.ps1
Provides utility functions used by the automation.
OSAbstractions.ps1
Functions that return a OS specific command line. This
was added when Integrated services were added to
FreeBSD.
A test run is driven by an XML file. A sample command might look
like the following:
.\lisa.ps1 run xml\debug_demo.xml -dbgLevel 5
The XML file has a number of key sections as follows:
Global
The global section defines settings used to specify where
the log files are to be written, who to send email to,
which email server to use, etc.
TestSuites
This section defines a test suite and lists all the test
cases the test suite will run.
TestCases
This section defines every test case that a test suite
might call. Test case definitions include the following:
Name of the test case
The test script to run on the VM
The file to push to the VM
Test case timeout value (in seconds)
What to do on error (stop testing or move on to next test case)
Test parameters
Test parameters are placed in a file named constants.sh
and then copied to the VM. The test case script can
source constants.sh to gain accesws to the test parameters.
VMs
The VMs section lists the VMs that will run tests. There will be a
VM definition for each VM that will run a test. Each VM can run
a separate test suite.
A very simple XML file would look something like the following:
<?xml version="1.0" encoding="utf-8"?>
<config>
<global>
<logfileRootDir>TestResults</logfileRootDir>
<defaultSnapshot>ICABase</defaultSnapshot>
<email>
<recipients>
<to>myboss@mycompany.com</to>
<to>myself@mycompany.com</to>
</recipients>
<sender>myself@mycompany.com</sender>

<smtpServer>mysmtphost.mycompany.com</smtpServer>
</email>
</global>

<testName>debug_demo_case</testName>
<testID>ESX-DEMO-001</testID>
<testScript>testscripts\debug_demo.ps1</testScript>
<RevertDefaultSnapshot>True</RevertDefaultSnapshot>
<timeout>120</timeout>
<onError>Continue</onError>
<noReboot>False</noReboot>
</test>
</testCases>
<VMs>
<vm>
<hvServer>ESXI_HOST_IPADDRESS</hvServer>
<vmName>VM_NAME</vmName>
<os>Linux</os>
<ipv4></ipv4>
<sshKey>demo_id_rsa.ppk</sshKey>
<suite>debug_demo_suite</suite>
</vm>
</VMs>
</config>
The automation scripts make some assumptions about the VMs
used to run the tests. This requires test VMs be provisioned
prior to running tests.
SSH keys are used to pass commands to Linux VMs, so the public
ssh Key must to copied to the VM before the test is started.
The dos2unix must be installed. It is used to ensure the file
has the correct end of line character.
The automation scripts currently use Putty as the SSH client.
You will need to copy the Putty executables to the lisa/bin
directory. You will also need to convert the private key into
a Putty Private Key (.ppk).
.Parameter cmdVerb
The command you wish to perform. Supported values include
run
help
.Parameter cmdNoun
The object the command verb is to operate on. Normally this
is the .xml file that defines the test suites, test cases and
VMs on which to perform tests.
.Parameter VMs
A subset of VMs to run the tests on. The list of VMs is defined
in the .xml file. The VMs parameter contains a subset of these
VMs. Tests will only be run on the subset of VMs rather than
all VMs defined in the .xml file.
.Parameter vmName
Name of a user supplied VM to run tests on. The test run will
use this VM to perform tests rather than the VMs listed in the
xml file.
.Parameter hvServer
The ESX server hosting the VM specified in the vmName argument.
.Parameter ipv4
The IPv4 address of the VM specified in the vmName argument.
.Parameter sshKey
The SSH key to use with the VM specified in the vmMane argument.
.Parameter suite
The test suite to use when running tests on the VM specified
in the vmName argument.
.Parameter testParams
VM specific test parameters to be used with the VM specified
in the vmName argument.
.Parameter email
email address to send test results to. This will be used rather than
the email list in the .xml file.
.Parameter examples
When requesting help, if the examples switch is specified, examples of
usage will be displayed.
.Parameter dbgLevel
The debug level to use when running tests. Values are 0 - 10. The higher
the value, the more verbose the logging of message. Levels above 5 are
quite chatty and are not recommended.
.Parameter NoShutDown
With this parameter lisa will exit and not shutdown virtual machine
after first case finished. This parameter helps debug test cases.
.Example
.\lisa.ps1 run xml\debug_demo.xml
.Example
.\lisa.ps1 run xml\debug_demo.xml -dbgLevel 5
.Link
None.
