Introduction
The Mobile-Connectivity (MobCon) LongHaul testing effort aims to improve and maintain the quality of connectivity solution that Microsoft provides for customers. Long-Haul testing framework identifies key scenarios in our connectivity solutions (Cellular, WiFi, NetworkUx and Connection-Awareness) and includes tests from those scenarios. These tests are executed in a randomized stress fashion for how-much-ever long (duration of execution can be passed as a parameter) that is specified by the tester. The intention of adding these tests is to identify issues and fix them before an end-user would hit such issues.
Test Setup
The test setup is exactly same as that of any other HLK test execution. You have a test machine and a host PC that is in the same subnet. The host PC will have Virtual HLK Controller (VHLK installed).
Test Execution
- Step 1 : Ensure that the test device is listed in the controller and is in Ready State
- Step 2 : Go to the Project tab and create a new project
- Step 3 : Go to the Selection tab and under "system" select our test PC
- Step 4 : Go to the Tests tab and select Mobcon longhaul test suite
Previous step of selecting the device should populate all the necessary tests in the "Tests" tab.
- Step 5 : Populate necessary parameters
Once you select the mobcon longhaul test suite and click "Run Selected", a window will pop-up showing a list of parameters as below :
Parameter List
| Variable Name | Meaning |
|---|---|
| RunSlotSwitchTest | Whether to execute the test case of switching cellular slot from physical SIM to ESIM and back. Acceptable values "TRUE" and "FALSE" |
| RunMPDPTest | Whether to execute the test case of Multiple PDP context data access. Acceptable values "TRUE" and "FALSE" |
| RunDownloadAndInstallProfileTest | Whether to execute the download and install of an ESIM profile. Acceptable values "TRUE" and "FALSE" |
| MPDPAccessString | AccessString to be used for second PDP context |
| subsystems | Chooses which tests to run based on selected subsystem(s). Cellular=0x01, Wi-Fi=0x02, CA=0x04, UI=0x08. To select multiple, use bitwise "|" (e.g. 0x03 = Cellular | Wi-Fi -- this selection will allow both the Cellular and Wi-Fi longhaul tests to run) |
| CustomTaefCommandArgs | Custom TAEF arguments that user can enter. Currently, support is limited to the default, auto-populated command arguments : "/randomstress /randomStressTimeout=0:00:30 /p:testmode=randomstress /enableStressLogging=false". Tester can modify randomStressTimeout to any value in format HOURS:MINUTES:SECONDS(H:MM:SS). Tester can also modify enableStressLogging as true or false [Setting this value to false will display all the logs on the command prompt in test device]. |
- Step 6 : Start the test
Once we populate the necessary parameters and press ok, the test will start running.
- Step 7 : Results
After the test is executed, go to the Results tab to retrieve the logs. We can get both te logs and NetTrace logs from the execution.
TestExecution logs :
NetTrace logs can be collected by rightclicking "Run Test" -> "Additional Files" -> "MobconLongHaulTests.etl"
