Technologies - TestNG Framework - What & Why?

What is TestNG

Its a New Generation Unit Testing framework, that is influenced by both JUnit and NUnit, but has more powerful features and is easier to use. It is designed with a good set of capabilities that simplify testing requirements ranging from functional, regression, end-to-end, and more

Why testNG:

1. Support for annotations -

Annotations in TestNG are lines of code that can control how the method below them will be executed. Annotations can use parameters just like the usual Java methods.

2. Support for parameterization - Static data using @Parameters

3. Support for Data Driven Testing using Data providers - Dynamic data

 

4. Enables user to set execution priorities & groups the test methods

5. Readily supports integration with various tools and plug-ins like build tools (Ant, Maven etc.),

6. Facilitates user with effective means of Report Generation using ReportNG. WebDriver has no native mechanism for generating reports, So TestNG can generate reports based on our Selenium test results.

7. The ability to run tests in parallel is available in TestNG but not in JUnit, so it is the more preferred framework of testers using Selenium Grid

 

8. Uncaught exceptions are automatically handled by TestNG without terminating the test prematurely. These exceptions are reported as failed steps in the report 

9. There is no more need for a static main method in our tests. The sequence of actions is regulated by easy-to-understand annotations that do not require methods to be static.

 

10. TestNG assertions – Hard & Soft asserts -The Assert class is used to conduct verification operations in TestNG

QA's approach 2 Java - Understanding Static context

            Static Members Flow Class members In java application we are defining objects for communication.Every Object is represented as a model(class). Hence, java application is the combination of classes. And every class in java application is allowed to define following members. 1) static members 2) non-static members Static members flow using JVM architecture : Java class supports definition of 4 static members. 1) static main method 2) static block 3) static variable 4) static method Static main method Example class Demo { //empty..... } How to Compile & Execute a simple Java program? 1) Save the program in "d-drive" with name Demo.java 2) Open command prompt, navigate to the path where the java program is stored 3) Compilation: cmd/> javac Demo.java Demo.class file will be generated. 4) Execution:  cmd/>java Demo Error : main method not found... main method : 1) It is static method, hence...

QA's approach 2 Java - Collections Framework & Generics Introduction

Why Collections & why is it called a Framework? First Question: Why Collections? Collections are used to overcome problems with variables, arrays, classes like size problem, type problem, non existence of predefined operations/methods, etc. To get a Overview of the above discussed problems, click on this link What is a Framework? Its a semi-finished re-usable application, providing some low level services, which can be customized according to our requirement.  Second Question: Why is it called a Framework? Collection API is available in util package & its called a Framework for the reason that, java programmers were not restricted to just utilize the existing classes making them final but was allowed to expand on top of the exiting classes inheriting them. Collections framework gives a clear example of when to use Interface & abstract class Classification of Collection Framework: In Collection Framework all the classes are classified into 3 cat...

Technologies - Log4J - Create Log4j Configuration File - Where ? How ? What ?

-
  Typical Steps involved in Creating Log4j Configuration file Configure the root logger - What to Log - info/debug/error/fatal messages Configure individual loggers (if needed). Specify appenders -- Where to Log -- in File/Console, etc Specify message layout/Pattern -- How to Log - format to log the message Configuring a Layout PatternLayout lets you determine how data is extracted from log events and formatted for output based on a conversion pattern. Conversion patterns act as placeholders for data that appears in each log event.  For example, let’s break down a PatternLayout commonly used in Log4j: <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/> %d{HH:mm:ss.SSS} formats the date in terms of hours, minutes, seconds, and milliseconds. %t displays the Logger’s current thread. %level displays the severity of the log event. %logger displays the name of the Logger. %m displays the event’s message. Finally, %n adds a new line for the next e...
