Hi Shilji,
I understand that you want to automate Simulink Test harness with spreadhseet based vectors. To automate the Simulink Test Harness with a spreadsheet-based test vector in Jenkins, you can follow these steps:
Install Required Plugins in Jenkins
- Git Plugin: For pulling code from your Gerrit repository. You may refer to the following documentation to learn more about Git plugin: https://plugins.jenkins.io/git/
- MATLAB Plugin: For running MATLAB scripts. You may refer to the following documentation to learn more about MATLAB plugin: https://plugins.jenkins.io/matlab/
- PostBuildScript Plugin: For executing a set of scripts at the end of the build. You may refer to the following documentation to learn more about PostScriptBuild plugin: https://plugins.jenkins.io/postbuildscript/
Create a New Job in Jenkins
Source Code Management:
- Select Git and configure your repository URL and credentials.
Additional Behaviors:
- Set up the following pattern to ignore builds if only HTML files have been committed to the SCM :
Test/.*\.html
Build Triggers:
- Since you are using Gerrit, you can set up a webhook in Gerrit to trigger the Jenkins job on code push. You can refer to the following documentation about 'Gerrit Trigger Plugin' : https://plugins.jenkins.io/gerrit-trigger/
Build Step:
- Add a build step to execute a MATLAB script that programatically reads values from spreadsheet and runs the test harness with the following code:
run("runHarness") % Change the name to your MATLAB script
Here, 'runHarness' is a .M file containing code to read data from an .XLSX file, create variables in the base workspace, and run the test harness. The test harness takes values from the base workspace for computation.
Here’s an example MATLAB script for simulating an internal test harness for the ‘Product’ block:
% Load the Simulink model
model = 'TestModel'; %Model Name
load_system(model);
% Get the handle of the subsystem or block for which the test harness is created
blockPath = [model, '/TestSubsystem'];
blockHandle = getSimulinkBlockHandle([model, '/TestSubsystem']);
% Read data from XLSX
table= readtable('Book1.xlsx');
A = table{:,1}
B = table{:,2}
% Open the test harness
harnessName = 'TestSubsystemHarness';
sltest.harness.open(blockHandle, harnessName);
simOut=sim(harnessName);
sltest.harness.close(blockHandle);
% Retrieve and compare results
actualResults = simOut.yout{1}.Values.Data;
Expected = A(1) .* B(1);
testPassed = isequal(actualResults, Expected);
% Generate a report
reportFile = 'TestReport.html';
file=fullfile('Report', reportFile)
fid = fopen(file, 'w');
fprintf(fid, '<html><body>\n');
fprintf(fid, '<h1>Test Report</h1>\n');
if testPassed
fprintf(fid, '<p>Test passed: Results match </p>\n');
else
fprintf(fid, '<p>Test failed: Results do not match</p>\n');
end
fprintf(fid, '<p>%s</p>\n', Expected);
fprintf(fid, '</body></html>\n');
fprintf(fid, '</body></html>\n');
fclose(fid)
Post-Build Actions:
- You can execute a .BAT or .SH file depending on the OS of the Jenkins environment to push the generated report to the repository.
Here’s an example batch script:
@echo off
git add Report/TestReport.html %git add <Location of the TestReport>
git commit -m "Add Simulink test report"
git push -f origin HEAD:main
Hope this helps!
