1.介绍
TestNG是一个测试框架，旨在简化广泛的测试需求，从单元测试（测试一个类别与其他类别隔离）到集成测试（测试整个系统由几个类，几个包甚至几个外部框架组成，如应用服务器）。
使用testng的流程基本是这样的：
编写测试用例在代码中
在testng.xml中添加配置测试用例了管理测试用例等。
运行testng
2.注释及其含义
| @BeforeSuite @AfterSuite @BeforeTest @AfterTest @BeforeGroups @AfterGroups @BeforeClass @AfterClass @BeforeMethod @AfterMethod |
Configuration information for a TestNG class: @BeforeSuite: The annotated method will be run before all tests in this suite have run. @AfterSuite: The annotated method will be run after all tests in this suite have run. @BeforeTest: The annotated method will be run before any test method belonging to the classes inside the <test> tag is run. @AfterTest: The annotated method will be run after all the test methods belonging to the classes inside the <test> tag have run. @BeforeGroups: The list of groups that this configuration method will run before. This method is guaranteed to run shortly before the first test method that belongs to any of these groups is invoked. @AfterGroups: The list of groups that this configuration method will run after. This method is guaranteed to run shortly after the last test method that belongs to any of these groups is invoked. @BeforeClass: The annotated method will be run before the first test method in the current class is invoked. @AfterClass: The annotated method will be run after all the test methods in the current class have been run. @BeforeMethod: The annotated method will be run before each test method. @AfterMethod: The annotated method will be run after each test method. Behaviour of annotations in superclass of a TestNG class The annotations above will also be honored (inherited) when placed on a superclass of a TestNG class. This is useful for example to centralize test setup for multiple test classes in a common superclass. In that case, TestNG guarantees that the "@Before" methods are executed in inheritance order (highest superclass first, then going down the inheritance chain), and the "@After" methods in reverse order (going up the inheritance chain). |
|
| alwaysRun | For before methods (beforeSuite, beforeTest, beforeTestClass and beforeTestMethod, but not beforeGroups): If set to true, this configuration method will be run regardless of what groups it belongs to. For after methods (afterSuite, afterClass, ...): If set to true, this configuration method will be run even if one or more methods invoked previously failed or was skipped. |
|
| dependsOnGroups | The list of groups this method depends on. | |
| dependsOnMethods | The list of methods this method depends on. | |
| enabled | Whether methods on this class/method are enabled. | |
| groups | The list of groups this class/method belongs to. | |
| inheritGroups | If true, this method will belong to groups specified in the @Test annotation at the class level. | |
| @DataProvider | Marks a method as supplying data for a test method. The annotated method must return an Object[][] where each Object[] can be assigned the parameter list of the test method. The @Test method that wants to receive data from this DataProvider needs to use a dataProvider name equals to the name of this annotation. | |
| name | The name of this data provider. If it's not supplied, the name of this data provider will automatically be set to the name of the method. | |
| parallel | If set to true, tests generated using this data provider are run in parallel. Default value is false. | |
| @Factory | Marks a method as a factory that returns objects that will be used by TestNG as Test classes. The method must return Object[]. | |
| @Listeners | Defines listeners on a test class. | |
| value | An array of classes that extend org.testng.ITestNGListener. | |
| @Parameters | Describes how to pass parameters to a @Test method. | |
| value | The list of variables used to fill the parameters of this method. | |
| @Test | Marks a class or a method as part of the test. | |
| alwaysRun | If set to true, this test method will always be run even if it depends on a method that failed. | |
| dataProvider | The name of the data provider for this test method. | |
| dataProviderClass | The class where to look for the data provider. If not specified, the data provider will be looked on the class of the current test method or one of its base classes. If this attribute is specified, the data provider method needs to be static on the specified class. | |
| dependsOnGroups | The list of groups this method depends on. | |
| dependsOnMethods | The list of methods this method depends on. | |
| description | The description for this method. | |
| enabled | Whether methods on this class/method are enabled. | |
| expectedExceptions | The list of exceptions that a test method is expected to throw. If no exception or a different than one on this list is thrown, this test will be marked a failure. | |
| groups | The list of groups this class/method belongs to. | |
| invocationCount | The number of times this method should be invoked. | |
| invocationTimeOut | The maximum number of milliseconds this test should take for the cumulated time of all the invocationcounts. This attribute will be ignored if invocationCount is not specified. | |
| priority | The priority for this test method. Lower priorities will be scheduled first. | |
| successPercentage | The percentage of success expected from this method | |
| singleThreaded | If set to true, all the methods on this test class are guaranteed to run in the same thread, even if the tests are currently being run with parallel="methods". This attribute can only be used at the class level and it will be ignored if used at the method level. Note: this attribute used to be called sequential (now deprecated). | |
| timeOut | The maximum number of milliseconds this test should take. | |
| threadPoolSize | The size of the thread pool for this method. The method will be invoked from multiple threads as specified by invocationCount. Note: this attribute is ignored if invocationCount is not specified |

要使用testng我们需要导入相关的jar包。

注意注释的内容都是在代码中使用的。今天先到这里后续会继续写xml文件的配置。
