MAINFRAME TESTING

SOFTWARE TESTING

The mainframe is high performance and high speed computer which can be used for larger scale of computing purposes like finance, insurance, retail where enormous data is processes many times. The mainframe testing is similar to web based testing. It is procedure to test mainframe systems. The mainframe testing is done on the deployed code for various data combinations set into input file. The software applications that run on the mainframe can be accessed by terminal emulator, which is a software needed to be installed on the client machine. While performing this mainframe testing, the tester needs to know the navigations of the CICS screen. The attributes of mainframe are:

  1. Viral storage: It is a procedure which lets the processor to simulate the main storage which is larger than the actual storage. It is a technique to use memory effectively to store and execute various sized jobs. It uses the disk storage space for an extension of real storage.
  2. Multiprogramming: The computer will execute more than one program at a time. But at a given time, only one program will have the control over the CPU.
  3. Batch Processing: It is a procedure in which the task is completed in the units which is called as jobs. A job will cause one or two programs to execute in a sequence. There is a job scheduler which makes the order of jobs which are to be executed first.
  4. Time Sharing: Each user will access the system through a terminal device. Instead of scheduling the jobs the user enters the command which can be processed immediately. It allows user to interact with the computer directly.
  5. Spooling: It stands for simultaneous peripheral operation online. It is a device to store output of a program or application. The spooled output is sent to output devices like printer.

Classification of manual testing in Mainframe:

  1. Batch job testing: This testing type of processes, involves the executions of batch job for the functionality implemented in the current release. The result of test are extracted from the files, for verification and recorded.
  2. Online testing: It is a testing technique which is very similar to web based testing. It includes testing of CICS screens. The functionality of the existing screen could be added or new screen could be changed.

  1. 1. Mainframe testing is the procedure toe test mainframe systems–which are associated with high performance and high speed computer. The advantage of mainframe testings is that it involves testing of larger scale of computing purposes (e.g. finance, insurance, retail, etc.).

    2.The attributes of mainframe:

    a. Viral storage: lets the processor simulate main storage (larger than actual storage);
    technique to use memory effectively to store and execute various sized jobs;
    uses the disk storage space for an extension of real storage.
    b. Multiprogramming: computer executes more than one program at a time.
    c. Batch Processing: procedure in which task is completed in units called jobs;
    job will cause one or two programs to execute in a sequence;
    involves a job scheduler which organizes the order in which jobs are to be scheduled
    d. Time Sharing: Each user will access the system through a terminal device;
    user enters the command which can be processed immediately;
    allows user to interact with the computer directly.
    e. Spooling: a device to store output of a program or application;
    spooled output is sent to output devices like printer.

    3. Mainframe testing has the following features associated with the testing approach:
    -Similar to web based testing
    -Test mainframe systems.
    -Done on the deployed code for various data combinations set into input file. –
    -Software applications that run on the mainframe accessed by terminal emulator (software needed to be installed on the client machine.)
    -Tester needs to know the navigations of the CICS screen.
    Examples (classifications):
    Batch job testing: involves the executions of batch job for the functionality implemented in the current release.
    Online testing: (similar to web based testing.) includes testing of CICS screens.

  2. The mainframe testing is the process of testing Software Services and Applications that are based on the Mainframe Systems. Mainframe Testing ensures that the system is ready to be launched in the market. It is done on the deployed code for various data combinations set into input file.
    Advantages: Mainframes can process enormous data at a reliable speed for years without any interruption. Mainframes are more stable than other computers. Mainframes are typically used by large-scale industries like finance, insurance, retail to perform/process their critical business applications
    Attributes are: Viral storage, Multi programming, Batch Processing, Time Sharing, Spooling.
    Example: Health Insurance company where they used Enormous data for customer records.

    –> Advantages of mainframe testing
    Reliability, scalability, security, availability, compatibility and customization.
    With Mainframe Testing DevOps teams can quickly setup testing environments for mainframe applications with critical dependent components and test data.
    Mainframe Testing ensures that the system is in fact, ready to be launched in the market.
    –>Attributes of mainframe testing
    1.Viral storage
    2.Multiprogramming
    3.Batch Processing
    4.Time Sharing
    5.Spooling
    –>For Example, testing of mainframe system of the anthem application like, testing the enrollment functionality for new and existing customers by providing plans based on zip code where they want the insurance.
