Add Plugin to Test Runner

This example shows how to add a plugin to the test runner. The

matlab.unittest.plugins.TestRunProgressPlugin displays progress messages

about a test case. This plugin is part of the matlab.unittest package. MATLAB® uses

it for default test runners.

Create a Test for the BankAccount Class

In a file in your working folder, create a test file for the BankAccount class.

type BankAccountTest.m

classdef BankAccountTest < matlab.unittest.TestCase

% Tests the BankAccount class.

methods (TestClassSetup)

function addBankAccountClassToPath(testCase)

p = path;

testCase.addTeardown(@path,p);

addpath(fullfile(matlabroot,'help','techdoc','matlab_oop',...

'examples'));

end

end

methods (Test)

function testConstructor(testCase)

b = BankAccount(1234, 100);

testCase.verifyEqual(b.AccountNumber, 1234, ...

'Constructor failed to correctly set account number');

testCase.verifyEqual(b.AccountBalance, 100, ...

'Constructor failed to correctly set account balance');

end

function testConstructorNotEnoughInputs(testCase)

import matlab.unittest.constraints.Throws;

testCase.verifyThat(@()BankAccount, ...

Throws('MATLAB:minrhs'));

end

function testDesposit(testCase)

b = BankAccount(1234, 100);

b.deposit(25);

testCase.verifyEqual(b.AccountBalance, 125);
