JCL Test Case Example

Your Micro Focus product contains an example unit test and JCL job card that you can use together with a JES-enabled enterprise server region. Run using the test runner syntax on the command line, you can run the unit test which will submit the job card to the enterprise server region, and then query the resulting return code of the JCL job and perform a number of test assertions.

The example source files are located in the C:\Documents and Settings\All Users\Documents\Micro Focus\Enterprise Developer\Samples\Mainframe\UnitTests\JCL_COBOL\Example1 directory.

txtdiff.jcl - the JCL job card. This job runs the IEBCOMPR utility to compare two blocks of data.
MFUT_TXTDIFF1.cbl - the test program that contains the unit test. The unit test uses JCL-specific metadata to identify the job card (MFU-MD-JCL-FILE-NAME), and then capture a number of job details (MFU-MD-JCL-COND-TYPE, MFU-MD-JCL-COND-CODE, and MFU-MD-JCL-JOB-NBR) after the test has run, then makes its test assertion by setting the MFU-MD-JCL-TESTCASE-PASSED variable accordingly (true or false).

To run the test, you also need a running JES-enabled enterprise server region - the following example uses a region called ESMFUJCL, and a catalog located in the c:\ESMFUJCL\ directory.

To run the example:

Compile the test program:
```
cbllink -D MFUT_TXTDIFF1.cbl
```
This produces the required executable test file.
Run the test, supplying details of the JES-enabled region and a JES catalog:
```
mfurun -sp -es-server-name:ESMFUJCL -es-syscat:c:\ESMFUJCL\CATALOG.DAT MFUT_TXTDIFF1.dll
```
The JCL job referenced in the unit test is submitted to the spool queue. The job requires a class A batch initiator, and so the test will wait, displaying the following output, if one is not already running within the region.
```
Fixture : MFUT_TXTDIFF1
 Executing test case : MFUT_TXTDIFF1
```

Start a batch initiator for class A, if required.

The test runs and a summary similar to the following should display:

Micro Focus COBOL - mfurun Utility

Test Run Summary
 Overall Result           Passed

During the test run, the generated report (MFUT_TXTDIFF1-report.txt) was read by the COBOL program in order to make the test assertions shown in the summary.
