使用脚本创建并运行测试用例

创建并运行基线测试用例

此示例展示如何使用 sltest.testmanager 函数、类和方法来自动化测试和生成报告。您可以以编程方式创建测试用例、编辑测试用例准则、运行测试用例、导出仿真输出并生成结果报告。该示例将模型的仿真输出与基线进行比较。

% Open the model for this example
openExample('sldemo_absbrake');

% Create the test file, test suite, and test case structure
tf = sltest.testmanager.TestFile('API Test File');
ts = createTestSuite(tf,'API Test Suite');
tc = createTestCase(ts,'baseline','Baseline API Test Case');

% Remove the default test suite
tsDel = getTestSuiteByName(tf,'New Test Suite 1');
remove(tsDel);

% Assign the system under test to the test case
setProperty(tc,'Model','sldemo_absbrake');

% Capture the baseline criteria
baseline = captureBaselineCriteria(tc,'baseline_API.mat',true);

% Test a new model parameter by overriding it in the test case
% parameter set
ps = addParameterSet(tc,'Name','API Parameter Set');
po = addParameterOverride(ps,'m',55);

% Set the baseline criteria tolerance for one signal
sc = getSignalCriteria(baseline);
sc(1).AbsTol = 9;

% Run the test case and return an object with results data
ResultsObj = run(tc);

% Get the test case result and the Sim Output run dataset
tcr = getTestCaseResults(ResultsObj);
runDataset = getOutputRuns(tcr);

% Open the Test Manager so you can view the simulation
% output and comparison data
sltest.testmanager.view;

% Generate a report from the results data
filePath = 'test_report.pdf';
sltest.testmanager.report(ResultsObj,filePath,...
          'Author','Test Engineer',...
          'IncludeSimulationSignalPlots',true,...
          'IncludeComparisonSignalPlots',true);

% Export the Sim Output run dataset
dataset = export(runDataset);

测试用例失败，因为仿真输出和基线准则之间的信号比较中只有一个在容差范围内。结果报告为 PDF 格式，完成后即可打开。有关更多报告生成设置，请参阅 sltest.testmanager.report 函数参考页。

创建并运行等效性测试用例

此示例比较两个仿真之间的信号数据以测试其等效性。

% Open the model for this example
openExample('sldemo_absbrake');

% Create the test file, test suite, and test case structure
tf = sltest.testmanager.TestFile('API Test File 1');
ts = createTestSuite(tf,'API Test Suite');
tc = createTestCase(ts,'equivalence','Equivalence Test Case');

% Remove the default test suite
tsDel = getTestSuiteByName(tf,'New Test Suite 1');
remove(tsDel);

% Assign the system under test to the test case
% for Simulation 1 and Simulation 2
setProperty(tc,'Model','sldemo_absbrake','SimulationIndex',1);
setProperty(tc,'Model','sldemo_absbrake','SimulationIndex',2);

% Add a parameter override to Simulation 1 and 2
ps1 = addParameterSet(tc,'Name','Parameter Set 1','SimulationIndex',1);
po1 = addParameterOverride(ps1,'Rr',1.20);

ps2 = addParameterSet(tc,'Name','Parameter Set 2','SimulationIndex',2);
po2 = addParameterOverride(ps2,'Rr',1.24);

% Capture equivalence criteria
eq = captureEquivalenceCriteria(tc);

% Set the equivalence criteria tolerance for one signal
sc = getSignalCriteria(eq);
sc(1).AbsTol = 2.2;

% Run the test case and return an object with results data
ResultsObj = run(tc);

% Open the Test Manager so you can view the simulation
% output and comparison data
sltest.testmanager.view;

在测试管理器结果的等效性准则结果部分中，yout.Ww 信号因容差而通过。其余信号比较均未通过，整体测试用例失败。

运行测试用例并收集覆盖率

此示例展示如何使用仿真测试用例收集覆盖率结果。要获得覆盖率，您需要 Simulink^® Coverage™ 许可证。

% Open the model for this example
openExample('sldemo_autotrans');

% Create the test file, test suite, and test case structure
tf = sltest.testmanager.TestFile('API Test File');
ts = createTestSuite(tf,'API Test Suite');
tc = createTestCase(ts,'simulation','Coverage Test Case');

% Remove the default test suite
tsDel = getTestSuiteByName(tf,'New Test Suite 1');
remove(tsDel);

% Assign the system under test to the test case
setProperty(tc,'Model','sldemo_autotrans');

% Turn on coverage settings at test-file level
cov = getCoverageSettings(tf);
cov.RecordCoverage = true;

% Enable MCDC and signal range coverage metrics
cov.MetricSettings = 'mr';

% Run the test case and return an object with results data
rs = run(tf);

% Get the coverage results
cr = getCoverageResults(rs);

% Open the Test Manager to view results
sltest.testmanager.view;

在测试管理器的结果和工件窗格中，点击“结果”。您可以查看汇总的覆盖率结果。

创建并运行测试用例迭代

此示例显示如何创建测试迭代。您可以以编程方式创建出现在测试用例的迭代部分中的表迭代。该示例创建了一个仿真测试用例，并为每次迭代分配一个信号编辑器场景。

% Open the model for this example
openExample('sldemo_autotrans');

% Create test file, test suite, and test case structure
tf = sltest.testmanager.TestFile('Iterations Test File');
ts = getTestSuites(tf);
tc = createTestCase(ts,'simulation','Simulation Iterations');

% Specify model as system under test
setProperty(tc,'Model','sldemo_autotrans');
 
% Set up table iteration
% Create iteration object
testItr1 = sltestiteration;
% Set iteration settings
setTestParam(testItr1,'SignalEditorScenario','Passing Maneuver');
% Add the iteration to test case
addIteration(tc,testItr1);

% Set up another table iteration
% Create iteration object
testItr2 = sltestiteration;
% Set iteration settings
setTestParam(testItr2,'SignalEditorScenario','Coasting');
% Add the iteration to test case
addIteration(tc,testItr2);

% Run test case that contains iterations
results = run(tc);

% Get iteration results
tcResults = getTestCaseResults(results);
iterResults = getIterationResults(tcResults);
