<h3>TestCaseProviders (NUnit 2.5)</h3>
|
|
|
|
<h4>Purpose</h4>
|
|
<p>TestCaseProviders are used with parameterized tests to provide the
|
|
specific test cases that will be used in calling the test.
|
|
|
|
<h4>Extension Point</h4>
|
|
<p>Addins use the host to access this extension point by name:
|
|
|
|
<pre>
|
|
IExtensionPoint listeners = host.GetExtensionPoint( "ParameterProviders" );</pre>
|
|
|
|
<h4>Interface</h4>
|
|
<p>The extension object passed to Install must implement either the
|
|
<b>ITestCaseProvider</b> or the <b>ITestCaseProvider2</b> interface:
|
|
|
|
<pre>
|
|
public interface ITestCaseProvider
|
|
{
|
|
bool HasTestCasesFor( MethodInfo method );
|
|
IEnumerable GetTestCasesFor( MethodInfo method );
|
|
}
|
|
|
|
public interface ITestCaseProvider2 : ITestCaseProvider
|
|
{
|
|
bool HasTestCasesFor( MethodInfo method, Test suite );
|
|
IEnumerable GetTestCasesFor( MethodInfo method, Test suite );
|
|
}
|
|
</pre>
|
|
|
|
<p>NUnit will call <b>ITestCaseProvider2</b> if it is available. Otherwise
|
|
<b>ITestCaseProvider</b> will be used.
|
|
|
|
<p><b>HasTestCasesFor</b> should return true if the provider is able to supply test cases
|
|
for the specified method. If a provider only wants to be used on certain types
|
|
of tests, it can examine the provided MethodInfo and the suite for which the
|
|
test is being constructed and return true or false based on what it finds.
|
|
|
|
<p>The GetParametersFor method should return a list of individual test cases.
|
|
Each test case may be expressed as a ParameterSet, as an array of arguments
|
|
or as a custom object containing one or more of the following properties:
|
|
|
|
<ul>
|
|
<li>Arguments
|
|
<li>RunState
|
|
<li>NotRunReason
|
|
<li>ExpectedExceptionType
|
|
<li>ExpectedExceptionName
|
|
<li>ExpectedExceptionMessage
|
|
<li>Result
|
|
<li>Description
|
|
<li>TestName
|
|
</ul>
|
|
|
|
<p>The ParameterSet class provides all these properties and may be used
|
|
to avoid the overhead of reflecting on the properties.
|
|
|
|
<h4>Notes:</h4>
|
|
|
|
<ol>
|
|
<li>Most providers will delegate one of the interface implementations
|
|
to the other if they implement both.
|
|
<li>TestCaseProviders that use data from the fixture class should use
|
|
<b>ITestCaseProvider2</b> interface so that they are able to access any
|
|
arguments supplied for constructing the fixture object.
|
|
<li>Providers that acquire data from outside the fixture will usually
|
|
be able to work with <b>ITestCaseProvider</b> alone.
|
|
<li>The <b>ITestCaseProvider2</b> interface was added in the NUnit 2.5.1 release.
|
|
</ol>
