| 27 | <h3>TestCaseBuilders (NUnit 2.4)</h3>
|
|---|
| 28 |
|
|---|
| 29 | <h4>Purpose</h4>
|
|---|
| 30 | <p>TestCaseBuilders create Tests based on a MethodInfo. NUnit uses several
|
|---|
| 31 | TestCaseBuilders internally to create various kinds of TestMethods.
|
|---|
| 32 |
|
|---|
| 33 | <h4>Extension Point</h4>
|
|---|
| 34 | Addins use the host to access this extension point by name:
|
|---|
| 35 |
|
|---|
| 36 | <pre>
|
|---|
| 37 | IExtensionPoint testCaseBuilders = host.GetExtensionPoint( "TestCaseBuilders" );</pre>
|
|---|
| 38 |
|
|---|
| 39 | <h4>Interfaces</h4>
|
|---|
| 40 | <p>The extension object passed to Install must implement either the ITestCaseBuilder
|
|---|
| 41 | or the ITestCaseBuilder2 interface:
|
|---|
| 42 |
|
|---|
| 43 | <pre>
|
|---|
| 44 | public interface ITestCaseBuilder
|
|---|
| 45 | {
|
|---|
| 46 | bool CanBuildFrom( MethodInfo method );
|
|---|
| 47 | Test BuildFrom( MethodInfo method );
|
|---|
| 48 | }
|
|---|
| 49 |
|
|---|
| 50 | public interface ITestCaseBuilder2 : ITestCaseBuilder
|
|---|
| 51 | {
|
|---|
| 52 | bool CanBuildFrom( MethodInfo method, Test suite );
|
|---|
| 53 | Test BuildFrom( MethodInfo method, Test suite );
|
|---|
| 54 | }
|
|---|
| 55 | </pre>
|
|---|
| 56 |
|
|---|
| 57 | <p>NUnit will call ITestCaseBuilder2 if it is available. Otherwise
|
|---|
| 58 | ITestCaseBuilder will be used.
|
|---|
| 59 |
|
|---|
| 60 | <p>The CanBuildFrom method should return true if the addin can build
|
|---|
| 61 | a test from the MethodInfo provided. Some TestCaseBuilder addins are only
|
|---|
| 62 | intended to apply to methods within a specific type of fixture. The
|
|---|
| 63 | suite argument of the ITestCaseBuilder2 interface may be used to make
|
|---|
| 64 | this determination.
|
|---|
| 65 |
|
|---|
| 66 | <p>The BuildFrom method should return a test constructed over the MethodInfo
|
|---|
| 67 | provided as an argument or null if the method cannot be used.
