Level 2 Test Procedure

The following functions are expecting to test the module operates correctly.

Test 1

Title Details
Function Name test_l2_dsHost_GetCPUTemperature
Description Get the CPU temperature and check whether the temperature falls within valid operating range and ensure the CPU is in a normal operating state based on maximum and minimum values of dsHost/cpuTemperature in the configuration file
Test Group 02
Test Case ID 001
Priority High

Pre-Conditions None

Dependencies None

User Interaction If user chose to run the test in interactive mode, then the test case has to be selected via console.

Test Procedure - Test 1

Variation / Steps Description Test Data Expected Result Notes
01 Initialize the host using dsHostInit No input parameters dsERR_NONE Should be successful
02 Get the CPU temperature using dsGetCPUTemperature cpuTemperature = valid buffer dsERR_NONE Should be successful
03 Check the CPU temperature against the profile cpuTemperature = obtained value, profile temperature range = dsHost/cpuTemperature of configuration file Value should fall in the expected range Should be successful
04 Terminate the host using dsHostTerm No input parameters dsERR_NONE Should be successful

Test 2

Title Details
Function Name test_l2_dsHost_GetAndVerifySocID
Description Get the SoC ID and verify with dsHost/socID value in configuration file
Test Group 02
Test Case ID 002
Priority High

Pre-Conditions None

Dependencies None

User Interaction If user chose to run the test in interactive mode, then the test case has to be selected via console.

Test Procedure - Test 2

Variation / Steps Description Test Data Expected Result Notes
01 Initialize the host using dsHostInit API No input parameters dsERR_NONE Should be successful
02 Get the SoC ID using dsGetSocIDFromSDK API socID = valid buffer dsERR_NONE Should be successful
03 Verify the SoC ID with the value in the configuration file socID = value from dsHost/socID of configuration file dsERR_NONE Should be successful
04 Terminate the host using dsHostTerm API No input parameters dsERR_NONE Should be successful

Test 3

Title Details
Function Name test_l2_dsHost_ValidateHostEDID_sink
Description Get the host EDID bytes and validate the EDID bytes and length with the dsHost/edidBytes and dsHost/edidbytesLength values from the configuration file
Test Group 02
Test Case ID 003
Priority High

Pre-Conditions None

Dependencies None

User Interaction If user chose to run the test in interactive mode, then the test case has to be selected via console.

Test Procedure - Test 3

Variation / Steps Description Test Data Expected Result Notes
01 Initialize the host using dsHostInit No input parameters dsERR_NONE Should be successful
02 Get the host EDID using dsGetHostEDID edid = valid buffer, length = valid pointer dsERR_NONE Should be successful
03 Validate the EDID bytes and length edid = retrieved EDID from dsHost/edidBytes of configuration file, length = retrieved length from dsHost/edidbytesLength of configuration file edidBytes and edidbytesLength from configuration file matches Should be successful
04 Terminate the host using dsHostTerm No input parameters dsERR_NONE Should be successful
