    Q21 Why Flash is required for every DUT? What we’re doing in Flash process?

    Ans. Flash (Flashing) is a process to install a new software (Build) on your newly DUT. So whenever a new device we got from our TL. we have to do flashing our device with latest software.

    Q22 What are AT & MMI commands? Which commands generally using in testing?

    Ans. The AT (ATtenstion) command and MMI (Man-Machine Interface) commands. Both are using to give instructions to Modem. Like:

    AT+ CFUN=? ==> to know CFUN: (0-1,4-7),(0-1),
    for example: AT+CFUN=1 ==> for Power on,
                         AT+CFUN=4 ==> for Power off
                         AT+CFUN=1,1 ==> for UE restart,

    General commands
    +CGMI=?
    Request manufacturer identification
    +CGMM=?
    Request model identification
    +CGMR=?
    Request revision identification
    +CGSN=?
    Request product serial number identification
    +CIMI=?
    Request international mobile subscriber identity
    Call control commands and methods
    +CSTA=?
    Select type of address
    +CMOD=[<mode>]


    eg +CMOD=1
    Call mode <mode>: integer type
    0 single mode
    1 alternating voice/fax
    2 alternating voice/data
    3 voice followed by data
    +CVMOD=[<voice_mode>]


    eg +CVMOD=2
    Voice Call Mode <voice_mode>: integer type
    0 CS_ONLY
    1 VOIP_ONLY
    2 CS_PREFERRED
    3 VOIP_PREFERRED
    +CHUP=?
    Hangup call

    Q23 How much the Size of Chipset/ and latest Chipset model Name?

    Ans. The size of chipset we measure in nm (nanometer). Chipset size examples are 12nm, 7nm, 5nm or 3nm. on 3nm we will start work around 2021. Model name i already define in Que no. 3.

    Q24 How to write Test Cases and Script?

    Ans.
    Test Case Design
    Script Design
    Test Case ID
    Script is a software which is written in
    Test Case Title
    development language eq: C, C++,Java
    Test Case Description
    or
    Test Case Requirements
    scripting language eg: Python, Perl, Shell, TTCN3
    Test procedure of Expected Result
    So scripts are written by developers and tester do only test the script like: verdict fail or pass.
    Reference
    But Tester require to know, at least basic knowledge of scripts 
    States


    Test Case Type


    Test case Priority


    Q25 Daily day-2-day Activities?

    Ans. Just reply back that i’ll go to my seat (1) check those mail which i sent yesterday for bugs reporting, (2) any new mail, (3) contact to Team Leader for today plan (4) check latest build, (5) reading specification and (6) product requirement and (7) specification requirement (8) Test Case design and after (9) your execution will start, and i written all execution details earlier.

    Q26 How much time Required in Test Case Execution?

    Ans. There’s a no fix time duration is define that, each Test Case will take equal amount of time for excecution. So if someone ask you a question how much time a Test Case will take for execution tell him clearly that how many total test cases we have for execution, a process will take such amount of time and, it’s not a fix time for every test case.
