Launching Galasa SimBank online

SimBank applications and a set of sample SimBank tests are located in the Galasa simplatform repository in GitHub. To start exploring the Galasa Simbank application and to run the sample SimBank tests by using the Galasa CLI, you need to complete the following steps:

  1. Clone the Galasa simplatform repository on your machine by running the following command in a terminal in the directory on your local machine in which you want to clone the repository files: 
    git clone https://github.com/galasa-dev/simplatform.git
  2. Run the ./build-locally.sh script to build the code.
  3. Run the ./run-locally.sh --server script to start the simbank server inside a local JVM.

In a few seconds, the terminal window displays a series of initialization messages, which on Windows looks like:

If you are a Mac or Linux user, the messages will be almost identical.

  1. The SimBank process has been launched, and is listening on port 2023 for Telnet connections, on port 2080 for web services connections and on port 2027 for Derby SQL connections. Neither web services or Derby connections are explored further in this section.

Manually exploring the SimBank application

When you launch SimBank, its banking application listens on port 2023 for incoming client Telnet connections, offering an opportunity to first connect to it manually to review and understand the (simulated) transactions it supports, before subjecting it to Galasa's provided tests.

Logging in to the simulated application

  1. With the Galasa SimBank component still running, configure your 3270 terminal emulator to access port 2023 of localhost (or IP address 127.0.0.1 if the localhost alias has not been set up) via the Telnet protocol. No SSL configuration is required.

  2. Connect to the listening Telnet service with your 3270 emulator and review the logon screen:

    SimBank logon screen

  3. Ensure that the cursor is in the Userid field - if it is not, use the TAB key to position it:

    TAB to the userid field

  4. Enter the userid IBMUSER

    Enter your userid

  5. Press TAB to move the cursor into the Password field, type the password SYS1 and press your 3270 terminal emulator's ENTER key to logon and transfer to the SimBank main menu:

    Banktest home screen

Note: Depending on your 3270 terminal emulator, its ENTER key may not be mapped to the physical ENTER key on your computer. For example, on PCOMM, by default, the ENTER key is mapped to the host machine's right CTRL key. If you are unsure about this, review your terminal emulator's documentation.

  1. Press PF1:

    CICS home screen

  2. Press your 3270 terminal emulator's CLEAR SCREEN key.

  3. Enter the transaction name BANK and press your 3270 terminal emulator's ENTER key once more to get to the SimBank main menu:

    Main banking menu

As you have been progressing through this process, selected events are logged to your terminal:

2019-08-16 09:26:39 INFO dev.galasa.simplatform.t3270.screens.AbstractScreen buildScreen Building Screen: SessionManagerLogon
2019-08-16 10:26:08 INFO dev.galasa.simplatform.saf.SecurityAuthorizationFacility authenticate User: IBMUSER authenticated

2019-08-16 10:30:10 INFO dev.galasa.simplatform.t3270.screens.AbstractScreen buildScreen Building Screen: CICSGoodMorning
2019-08-16 10:36:19 INFO dev.galasa.simplatform.t3270.screens.AbstractScreen buildScreen Building Screen: CICSClearScreen
2019-08-16 10:38:54 INFO dev.galasa.simplatform.t3270.screens.AbstractScreen buildScreen Building Screen: BankMainMenu

This is an example of log output that can be useful when running tests.

Browsing account information

  1. From the SimBank main menu, press PF1, taking you to the account menu screen.

  2. Press TAB until the cursor is in the Account Number field, enter 123456789 and press ENTER. The account details are populated and it is apparent that account number 123456789 is 56.72 in credit.

    Account balance

  3. Press PF3 to return to the account menu screen.

Transferring funds between accounts

  1. From the SimBank main menu, press PF4, taking you to the SimBank transfer menu.

  2. Press TAB until the cursor is in the Transfer from Account Number field and enter 123456789.

  3. Press TAB until the cursor is in the Transfer to Account Number field and enter 987654321.

  4. Press TAB until the cursor is in the Transfer Amount field and enter 1

    Inter-account transfer

  5. Press ENTER - a Transfer Successful message appears. A log message is also written to the terminal:

2019-08-16 13:50:53 INFO dev.galasa.simplatform.application.Bank transferMoney Transfering  1.0 from account: 123456789 to account: 987654321

Press PF3 and once again browse the 123456789 account as described previously to verify that its total credit has decreased by the transferred 1.00, and that the 987654321 account has increased by the same amount.

Note that SimBank also offers a web services interface on port 2080, and although it is not exercised in this topic, it is used by two of the provided tests - BasicAccountCreditTest.java and ProvisionedAccountCreditTests.java.

Having explored SimBank manually, it's a good time to run some or all of a small collection of automated tests that are provided with SimBank itself - to start, choose Running the supplied SimBank tests online.
