Open Live Script

This example shows how to get and set the PreSaveFcn callback for a requirement set.

Add the current folder to the path.

addpath(pwd)

Open the ShortestPath project that contains an algorithm to calculate the shortest path between two nodes on a graph. For more information, see Verify a MATLAB Algorithm by Using Requirements-Based Tests.

openProject("ShortestPath");

Open the shortest_path_tests_reqs requirement set. The requirement set contains test requirements that describe the functional behavior that must be tested by a test case in order to verify the shortest_path algorithm in the project.

testReqs = slreq.open("shortest_path_tests_reqs");

Register the preSaveTestReqs script as the PreSaveFcn callback.

setPreSaveFcn(testReqs,"preSaveTestReqs");

Confirm that the preSaveTestReqs script is the PreSaveFcn callback for the shortest_path_tests_reqs requirement set.

callbackScript = getPreSaveFcn(testReqs)
callbackScript = 
'preSaveTestReqs'

Save the shortest_path_tests_reqs requirement set to execute the callback.

save(testReqs);

The preSaveTestReqs script saves the current Requirements Editor view settings to a MAT-file called myViewSettings.mat.

type preSaveTestReqs.m
slreq.exportViewSettings("myViewSettings.mat");
