TestNG Annotations and Attributes
TestNG is a extremely fashionable testing framework utilized in Java functions. It supplies a number of annotations and attributes that can help you management the conduct and execution of your assessments. Let’s check out a few of the generally used TestNG annotations and attributes:
@Check
This explicit annotation serves the aim of designating a way as a take a look at technique. TestNG considers strategies annotated with @Check as take a look at instances to be executed.
Instance:
@Check
public void testMethod() {
// Check code goes right here
}
@BeforeSuite
This annotation is used to designate a way that one ought to run earlier than any take a look at suite within the take a look at execution. It’s sometimes used for establishing any world configurations or assets required for the whole suite.
Instance:
@BeforeSuite
public void setupBeforeSuite() {
// International setup code goes right here
}
@AfterSuite
This annotation is used to designate a way one ought to run after all of the take a look at suites have been executed. It’s sometimes used for performing cleanup actions or releasing any assets acquired throughout the take a look at execution.
Instance:
@AfterSuite
public void cleanupAfterSuite() {
// Cleanup code goes right here
}
@BeforeTest
This annotation is used to designate a way that one ought to run earlier than every take a look at in a <take a look at> tag within the testng.xml file. It’s sometimes used for test-specific setup actions.
Instance:
@BeforeTest
public void setupBeforeTest() {
// Check-specific setup code goes right here
}
@AfterTest
This annotation is used to designate a way that one ought to run after every take a look at in a <take a look at> tag within the testng.xml file. It’s sometimes used for test-specific cleanup actions.
Instance:
@AfterTest
public void cleanupAfterTest() {
// Check-specific cleanup code goes right here
}
These are only a few examples of TestNG annotations. TestNG supplies many extra annotations that can help you management take a look at execution, set priorities, group assessments, deal with dependencies, and extra.
Along with annotations, TestNG additionally supplies a number of attributes that one can use together with the annotations to customise the conduct of your assessments additional. Listed below are some generally used attributes:
Precedence
This attribute permits you to assign a precedence to your take a look at strategies. TestNG will execute the take a look at strategies in ascending order of their priorities.
Instance:
@Check(precedence = 1)
public void highPriorityTest() {
// Check code goes right here
}
@Check(precedence = 2)
public void lowPriorityTest() {
// Check code goes right here
}
DependsOnMethods
This attribute specifies the strategies {that a} explicit take a look at technique is determined by. TestNG will be sure that the dependent strategies are executed earlier than the take a look at technique.
Instance:
@Check
public void loginTest() {
// Login code goes right here
}
@Check(dependsOnMethods = “loginTest”)
public void homePageTest() {
// Dwelling web page take a look at code goes right here
}
DataProvide
This attribute is used to specify the identify of the information supplier technique that provides take a look at information to the take a look at technique.
Instance:
@Check(dataProvider = “userData”)
public void createUserTest(String username, String password) {
// Check code goes right here
}
@DataProvider(identify = “userData”)
public Object[][] provideUserData() {
// Information supplier code goes right here
}
Teams
This attribute permits you to assign take a look at strategies to completely different teams. It helps in organizing and categorizing your assessments.
Instance:
@Check(teams = “smoke”)
public void smokeTest1() {
// Smoke take a look at 1 code goes right here
}
@Check(teams = “smoke”)
public void smokeTest2() {
// Smoke take a look at 2 code goes right here
}
@Check(teams = “regression”)
public void regressionTest() {
// Regression take a look at code goes right here
}
These are only a few examples of TestNG attributes. TestNG supplies many extra attributes to manage take a look at conduct, information dealing with, parallel execution, and extra.
What’s Parameterization?
In the true world, it’s all the time fascinating for our system to carry out successfully with completely different enter information units. The identical applies to testing as properly. In testing, we have to be sure that our system can deal with varied combos of information, as anticipated, throughout automated assessments. That is the place the idea of ‘Parameterization’ performs a vital position in automation testing.
We have to parameterise our take a look at scripts to supply a number of units of knowledge to the applying at runtime. This idea, generally known as Information-driven Testing, permits us to execute a take a look at case a number of occasions with completely different enter values robotically. By adopting this take a look at design, we are able to retrieve information from storage, similar to a file or database, as an alternative of utilizing hardcoded values. Because the Selenium WebDriver automation device has no built-in construction or method for parameterizing take a look at instances, we are able to make the most of the TestNG testing framework.
Key Insights
TestNG performs a vital position in enhancing automated assessments’ construction, readability, maintainability, and user-friendliness. It gives a variety of highly effective options and complete reporting capabilities. Leveraging TestNG’s superior annotations, significantly the information supplier, makes it simpler to scale up your testing efforts, particularly when performing cross-browser testing across a number of gadgets, browsers, and their respective variations utilizing LambdaTest.
It’s vital to notice that LambdaTest helps operating Selenium assessments utilizing each TestNG and JUnit, offering flexibility in your testing framework selection.
If you’re within the means of automating your take a look at instances and choosing the appropriate framework, it’s important to rigorously take into account your present wants and utilization as an engineering perform.
Moreover, take into consideration future scalability necessities. By assessing these elements, you can also make an knowledgeable choice in regards to the framework that finest aligns along with your particular necessities.
