Hi Saurabh,
One way to handle this is by leveraging the ‘preLoadFcn’ property of your test cases.
1. Create a Preload Function: Write a function that calculates the path to your MAT file relative to the common base directory and sets this path in a way that your test can use it.
function preloadFunction(testCase)
basePath = fileparts(which('yourTestFile.m'));
relativePathToMat = fullfile(basePath, 'relative', 'path', 'to', 'yourMatFile.mat');
testCase.TestData.matFilePath = relativePathToMat;
2. Configure Your Test to Use the Preload Function: In the Test Manager or your test script, set the ‘preLoadFcn’ property of your test case to point to the preload function you just created.
I Hope it helps!
