Generate HTML test report from test results

Since R2022a

Syntax

generateHTMLReport(results)

generateHTMLReport(results,folderName)

generateHTMLReport(___,Name=Value)

Description

generateHTMLReport(results) generates a test report from the test results in HTML format and saves it to a temporary folder. By default, the method names the main file of the report index.html.

Use this method to generate an HTML test report once the test run is complete and the test results are available.

generateHTMLReport(results,folderName) saves the report to the specified folder.

generateHTMLReport(___,Name=Value) specifies options using one or more name-value arguments in addition to any of the input argument combinations in previous syntaxes. For example, generateHTMLReport(results,MainFile="main.html") generates a test report whose main file is main.html.

Input Arguments

results — Test results

matlab.unittest.TestResult array

Test results, specified as a matlab.unittest.TestResult array.

folderName — Name of test report folder

string scalar | character vector

Name of the test report folder, specified as a string scalar or character vector. If you specify a relative path, the path must be in the current folder. Otherwise, you must specify a full path.

Example: "myTestReport"

Example: "C:\work\myTestReport"

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: generateHTMLReport(results,MainFile="main.html") generates a test report whose main file is main.html.

MainFile — Name of main HTML file

string scalar | character vector

Name of the main HTML file, specified as a string scalar or character vector ending in .html or .htm. If not specified, the method names the main file of the report index.html.

Example: MainFile="main.html"

Title — Title of test report

string scalar | character vector

Title of the test report, specified as a string scalar or character vector. By default, the method uses "MATLAB® Test Report" as the title.

Example: Title="My Test Report"

Examples

Generate HTML Report After Running Tests

Run a suite of tests and then generate an HTML test report from the test results.

Create a function-based test sampleTest.m in your current folder. The file contains two tests that pass and one test that fails.

function tests = sampleTest
tests = functiontests(localfunctions);
end

function testA(testCase)      % Test passes
verifyEqual(testCase,2+3,5)
end

function testB(testCase)      % Test fails
verifyGreaterThan(testCase,13,42)
end

function testC(testCase)      % Test passes
verifySubstring(testCase,"Hello World!","llo")
end

Run the tests in sampleTest.m.

results = runtests("sampleTest");

Limitations

• A test report generated by the generateHTMLReport method does not include the text output from the Command Window.

Tips

• When you generate a test report from test results that are created by a default runner, the report includes diagnostics for failing events and messages logged at the matlab.automation.Verbosity.Terse level. To generate a test report that includes diagnostics for passing events or messages logged at different verbosity levels, first customize your test run by adding a DiagnosticsRecordingPlugin instance to the runner. For example, run your tests and generate a test report that includes passing diagnostics and messages logged at all verbosity levels.

  import matlab.unittest.plugins.DiagnosticsRecordingPlugin
  import matlab.automation.Verbosity
  suite = testsuite("sampleTest");
  runner = testrunner("minimal");
  runner.addPlugin(DiagnosticsRecordingPlugin( ...
      IncludingPassingDiagnostics=true,LoggingLevel=Verbosity.Verbose))
  results = run(runner,suite);
  generateHTMLReport(results)

• To generate a test report without explicitly collecting the test results, customize your test run by adding a TestReportPlugin instance to the test runner.
