matlab.unittest.TestSuite.fromFile
Class: matlab.unittest.TestSuite
Namespace: matlab.unittest
Create test suite from test file
Syntax
Description
suite = matlab.unittest.TestSuite.fromFile(
creates a test suite from the tests in the specified file and returns the test suite as a
file
)matlab.unittest.TestSuite
array.
To run the test suite, the testing framework changes the current folder to the folder that defines the test content and adds it to the path for the duration of the test run.
suite = matlab.unittest.TestSuite.fromFile(___,
specifies options using one or more name-value arguments in addition to the input argument
combinations in previous syntaxes. For example, Name,Value
)suite =
matlab.unittest.TestSuite.fromFile("myFile.m","Name","featureA_*")
creates a
test suite that includes only the tests whose name starts with
"featureA_"
from myFile.m
.
Input Arguments
file
— Name of test file
string scalar | character vector
Name of the test file, 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: "myFile.m"
Example: "C:\work\myFile.m"
selector
— Selector
instance of selector class
Selector, specified as an instance of a class in the matlab.unittest.selectors
namespace. If you have a MATLAB®
Test™ license, you also can specify selector
as a
matlabtest.selectors.DependsOn
or
matlabtest.selectors.HasBaseline
instance.
Example: matlab.unittest.selectors.HasTag
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: suite =
matlab.unittest.TestSuite.fromFile("myFile.m",Name="featureA_*")
Before R2021a, use commas to separate each name and value, and enclose
Name
in quotes.
Example: suite =
matlab.unittest.TestSuite.fromFile("myFile.m","Name","featureA_*")
ExternalParameters
— External parameters to use in tests
array of matlab.unittest.parameters.Parameter
objects
External parameters to use in the tests, specified as an array of matlab.unittest.parameters.Parameter
objects. Use this argument to specify
external parameters instead of the existing parameters in a parameterized test. For more
information, see Use External Parameters in Parameterized Test.
BaseFolder
— Name of base folder
string array | character vector | cell array of character vectors
Name of the base folder that contains the test file, specified as a string array, character
vector, or cell array of character vectors. This argument
filters the test suite. For the testing framework to include a
test in the filtered suite, the Test
element
must be contained in one of the base folders specified by
BaseFolder
. If none of the
Test
elements match a base
folder, an empty test suite is returned. Use the wildcard
character (*
) to match any number of
characters. Use the question mark character
(?
) to match a single
character.
For test files defined in namespaces, the base folder is the parent of the top-level namespace folder.
DependsOn
— Names of files and folders that contain source code
string vector | character vector | cell vector of character vectors
Names of the files and folders that contain source code, specified as a string vector, character vector, or cell vector of character vectors. This argument filters the test suite. For the testing framework to include a test in the filtered suite, the file that defines the test must depend on the specified source code. If none of the test files depend on the source code, an empty test suite is returned.
The specified value must represent at least one existing file. If you specify a folder, the framework extracts the paths to the files within the folder.
You must have a MATLAB
Test license to use DependsOn
. For more information about
selecting tests by source code dependency, see matlabtest.selectors.DependsOn
(MATLAB Test).
Example: DependsOn=["myFile.m" "myFolder"]
Example: DependsOn=["folderA" "C:\work\folderB"]
Name
— Name of test
string array | character vector | cell array of character vectors
Name of the test, specified as a string array, character vector, or cell array of
character vectors. This argument filters the test suite. For the testing framework to
include a test in the filtered suite, the Name
property of the
Test
element must match one of the names specified by
Name
. If none of the Test
elements have a
matching name, an empty test suite is returned. Use the wildcard character
(*
) to match any number of characters. Use the question mark
character (?
) to match a single character.
For a given test file, the name of a test uniquely identifies the smallest runnable portion of the test content. The test name includes the namespace name, filename (excluding the extension), procedure name, and information about parameterization.
ParameterProperty
— Name of parameterization property
string array | character vector | cell array of character vectors
Name of a test class property that defines a parameter used by the test, specified as a string
array, character vector, or cell array of character vectors. This argument filters the
test suite. For the testing framework to include a test in the filtered suite, the
Parameterization
property of the Test
element
must contain at least one of the property names specified by
ParameterProperty
. If none of the Test
elements have a matching property name, an empty test suite is returned. Use the
wildcard character (*
) to match any number of characters. Use the
question mark character (?
) to match a single character.
ParameterName
— Name of parameter
string array | character vector | cell array of character vectors
Name of a parameter used by the test, specified as a string array, character vector, or cell array of character vectors. MATLAB generates parameter names based on the test class property that defines the parameters. For example:
If the property value is a cell array, MATLAB generates parameter names from the elements of the cell array by taking into account their values, types, and dimensions.
If the property value is a structure, MATLAB generates parameter names from the structure fields.
The ParameterName
argument filters the test suite. For the testing
framework to include a test in the filtered suite, the
Parameterization
property of the
Test
element must contain at least one of the
parameter names specified by ParameterName
. If none of
the Test
elements have a matching parameter name, an
empty test suite is returned. Use the wildcard character
(*
) to match any number of characters. Use the
question mark character (?
) to match a single
character.
ProcedureName
— Name of test procedure
string array | character vector | cell array of character vectors
Name of the test procedure, specified as a string array, character vector, or cell
array of character vectors. This argument filters the test suite. For the testing
framework to include a test in the filtered suite, the ProcedureName
property of the Test
element must match one of the procedure names
specified by ProcedureName
. If none of the Test
elements have a matching procedure name, an empty test suite is returned. Use the
wildcard character (*
) to match any number of characters. Use the
question mark character (?
) to match a single character.
In a class-based test, the name of a test procedure is the name of a
Test
method that contains the test. In a function-based test, it
is the name of a local function that contains the test. In a script-based test, it is a
name generated from the test section title. Unlike the name of a test suite element, the
name of a test procedure does not include any namespace name, filename, or information
about parameterization.
Superclass
— Name of class that test class derives from
string array | character vector | cell array of character vectors
Name of the class that the test class derives from, specified as a string array,
character vector, or cell array of character vectors. This argument filters the test
suite. For the testing framework to include a test in the filtered suite, the
TestClass
property of the Test
element must
point to a test class that derives from one of the classes specified by
Superclass
. If none of the Test
elements match
a class, an empty test suite is returned.
Tag
— Name of tag
string array | character vector | cell array of character vectors
Name of a tag used by the test, specified as a string array, character vector, or cell
array of character vectors. This argument filters the test suite. For the testing
framework to include a test in the filtered suite, the Tags
property
of the Test
element must contain at least one of the tag names
specified by Tag
. If none of the Test
elements
have a matching tag name, an empty test suite is returned. Use the wildcard character
(*
) to match any number of characters. Use the question mark
character (?
) to match a single character.
Examples
Create Test Suites from Test File
Create test suites from a test file by using the fromFile
static method.
In a file named ZerosTest.m
in your current folder, create the ZerosTest
class, which tests the zeros
function.
classdef ZerosTest < matlab.unittest.TestCase properties (TestParameter) type = {'single','double','uint16'}; size = struct("s2d",[3 3],"s3d",[2 5 4]); end methods (Test) function testClass(testCase,size,type) testCase.verifyClass(zeros(size,type),type) end function testSize(testCase,size) testCase.verifySize(zeros(size),size) end function testDefaultClass(testCase) testCase.verifyClass(zeros,"double") end function testDefaultSize(testCase) testCase.verifySize(zeros,[1 1]) end function testDefaultValue(testCase) testCase.verifyEqual(zeros,0) end end end
Import the classes used in this example.
import matlab.unittest.TestSuite import matlab.unittest.selectors.HasParameter
Create a test suite from the ZerosTest.m
file and display the test names. The suite contains 11 Test
elements.
suite = TestSuite.fromFile("ZerosTest.m");
disp({suite.Name}')
{'ZerosTest/testClass(size=s2d,type=single)'} {'ZerosTest/testClass(size=s2d,type=double)'} {'ZerosTest/testClass(size=s2d,type=uint16)'} {'ZerosTest/testClass(size=s3d,type=single)'} {'ZerosTest/testClass(size=s3d,type=double)'} {'ZerosTest/testClass(size=s3d,type=uint16)'} {'ZerosTest/testSize(size=s2d)' } {'ZerosTest/testSize(size=s3d)' } {'ZerosTest/testDefaultClass' } {'ZerosTest/testDefaultSize' } {'ZerosTest/testDefaultValue' }
Create a test suite that includes only the parameterized tests from the ZerosTest.m
file.
suite1 = TestSuite.fromFile("ZerosTest.m",HasParameter);
disp({suite1.Name}')
{'ZerosTest/testClass(size=s2d,type=single)'} {'ZerosTest/testClass(size=s2d,type=double)'} {'ZerosTest/testClass(size=s2d,type=uint16)'} {'ZerosTest/testClass(size=s3d,type=single)'} {'ZerosTest/testClass(size=s3d,type=double)'} {'ZerosTest/testClass(size=s3d,type=uint16)'} {'ZerosTest/testSize(size=s2d)' } {'ZerosTest/testSize(size=s3d)' }
Create a test suite that includes only the tests whose name contains "Class"
from the ZerosTest.m
file.
suite2 = TestSuite.fromFile("ZerosTest.m","Name","*Class*"); disp({suite2.Name}')
{'ZerosTest/testClass(size=s2d,type=single)'} {'ZerosTest/testClass(size=s2d,type=double)'} {'ZerosTest/testClass(size=s2d,type=uint16)'} {'ZerosTest/testClass(size=s3d,type=single)'} {'ZerosTest/testClass(size=s3d,type=double)'} {'ZerosTest/testClass(size=s3d,type=uint16)'} {'ZerosTest/testDefaultClass' }
Version History
Introduced in R2013aR2024a: Specify any type of source file when filtering test suite by source code dependency
If you have a MATLAB
Test license, you can specify any type of source file using the
DependsOn
name-value argument or the
matlabtest.selectors.DependsOn
class. In previous releases, you can
specify files only with a .m
, .p
,
.mlx
, .mlapp
, .mat
, or
.slx
extension.
R2023a: Filter test suite by source code dependency
If you have a MATLAB
Test license, you can filter a test suite by test file dependency on specified
source code. Use the DependsOn
name-value argument or the
matlabtest.selectors.DependsOn
class to specify the source files and
folders.
R2022b: Parameter names generated from cell arrays are more descriptive
When you assign a nonempty cell array to a parameterization property, the testing framework generates parameter names from the elements of the cell array by taking into account their values, types, and dimensions. In previous releases, if the property value is a cell array of character vectors, the framework generates parameter names from the values in the cell array. Otherwise, the framework specifies parameter names as value1
, value2
, …, valueN
.
If your code uses parameter names to create or filter test suites, replace the old parameter
names with the descriptive parameter names. For example, update suite =
testsuite(pwd,"ParameterName","value1")
by replacing value1
with a descriptive parameter name.
