 The Difference Between UX and UI Design:

UI design: 
UI design (or user interface design) focuses on the visual, interactive elements of the product. It designs all the screens and components that the user interacts with. It’s about creating digital products that are both aesthetically pleasing and flawlessly functional.

UX Design:
UX design (or user experience design) focuses on how intuitive, easy, and enjoyable it is to use a product (like a website or an app). It involves conducting research to understand user needs, and mapping out a logical structure and flow for the product.

Playwright vs Selenium > Key Differences in Playwright vs Selenium:

 Selenium and Playwright are both powerful web automation tools, but they differ in architecture, speed, browser support, and community adoption. While Selenium has been the industry standard for years, Playwright offers modern features and faster execution.

What Is Selenium?

Selenium was created in 2004 by Jason Huggins at ThoughtWorks as a JavaScript-based tool for testing web applications, initially named Selenium Core. Over time, the project expanded into Selenium Remote Control (RC) and other components. In 2008, Simon Stewart introduced Selenium WebDriver, a modern and robust browser automation framework that revolutionized the project by directly communicating with browsers through their native automation APIs. Today, Selenium is an open-source project maintained by a global community and is widely regarded as the standard for browser automation.

Selenium has become a comprehensive ecosystem for testing web applications across browsers and platforms.

Key Components of Selenium

  1. Selenium WebDriver: The core of Selenium, WebDriver provides a programming interface to control browser behavior. It allows you to simulate user interactions with web elements, navigate pages, and perform actions just as a real user would.
  2. Selenium IDE (Integrated Development Environment): A browser extension that enables testers to record, edit, and playback test scripts. It's particularly useful for creating quick tests or for those new to test automation. The Selenium IDE as a browser extension is soon being replaced by an Electron application that will provide more capabilities for all users.
  3. Selenium Grid: This component allows you to run your tests in parallel across different machines and browser configurations, significantly reducing the time required for large test suites.

Selenium's Strengths

  • Wide Browser Compatibility: Selenium supports a broad range of browsers, including older versions, which is crucial for applications that cater to diverse user bases.
  • Language Flexibility: Selenium integrates well with various technology stacks, with bindings for Java, Python, C#, Ruby, and JavaScript, among others.
  • Extensive Community and Resources: Thanks to its long-standing presence, Selenium boasts a vast community, comprehensive documentation, and a wealth of third-party tools and extensions.

Selenium's robustness and flexibility have become a staple in many organizations' testing strategies. However, as we'll see, the newer Playwright framework offers its own compelling features.

 

What Is Playwright?

Playwright is a modern, open-source framework for end-to-end testing of web applications. Developed by Microsoft and first released in 2020, Playwright is based on Puppeteer concepts (such as using CDP as a protocol) and expands its capabilities to support multiple browsers. Puppeteer is a browser automation tool for Chromium browsers and runs the browser headless by default but can also run the browser conventionally. Puppeteer is based on CDP (Chrome Devtools Protocol), Playwright’s foundation.  

Key Features of Playwright

  1. Multi-Browser Support: Playwright can automate Chromium, Firefox (a modified open source version, not the typical end-user one), and WebKit (another modified open source version) with a single API, covering all major rendering engines.
  2. Multiple Language Bindings: While primarily based on Node.js, Playwright offers bindings for TypeScript, JavaScript, Python, .NET, and Java.
  3. Powerful Tooling: Playwright has a built-in tool suite:
    • Codegen: Generates test scripts by recording user actions.
    • Playwright Inspector: Allows for real-time debugging and element inspection.
    • Trace Viewer: Provides comprehensive test failure analysis with screencasts, DOM snapshots, and action logs.

Playwright's Strengths

  • Modern Web App Testing: Playwright excels at handling complex, dynamic web applications with features like auto-waiting and network interception.
  • Speed and Efficiency: Its use of WebSocket communication and a single browser instance for multiple contexts results in faster test execution.
  • Cross-Browser Testing: Playwright simplifies cross-browser testing workflows with built-in support for Chromium and any the Playwright team modifies.

Playwright's modern approach and powerful features have quickly made it a favorite among developers looking for efficient and reliable test automation solutions.

 

Selenium vs Playwright: A Head-to-Head Comparison:

Comparing a browser automation tool like Selenium to a testing framework like Playwright would be deceptive. While Playwright aims to solve the challenge of web application testing, Selenium aims to solve the challenge of browser automation across different browser engines in a standardized way. 

Let's break down these differences to help you determine which framework might be the best fit for your project.

Database Testing


Database testing means test engineer should test the data integrity, data accessing,query retriving,modifications,updation and deletion etc 

Types of testings and processes

Black Box Testing in Database testing

Black box testing involves testing interfaces and the integration of the database, which includes:
1.   Mapping of data (including metadata)
2.   Verifying incoming data
3.   Verifying outgoing data from query functions
4.   Various techniques such as Cause effect graphing technique, equivalence partitioning and boundary-value analysis.
With the help of these techniques, the functionality of the database can be tested thoroughly.
Pros and Cons of black box testing include: Test case generation in black box testing is fairly simple. Their generation is completely independent of software development and can be done in an early stage of development. As a consequence, the programmer has better knowledge of how to design the database application and uses less time for debugging. Cost for development of black box test cases is lower than development of white box test cases. The major drawback of black box testing is that it is unknown how much of the program is being tested. Also, certain errors cannot be detected.


White Box Testing in database testing

White box testing mainly deals with the internal structure of the database. The specification details are hidden from the user.
1.   It involves the testing of database triggers and logical views which are going to support database refactoring.
2.   It performs module testing of database functions, triggers, views, SQL queries etc.
3.   It validates database tables, data models, database schema etc.
4.   It checks rules of Referential integrity.
5.   It selects default table values to check on database consistency.
6.   The techniques used in white box testing are condition coverage, decision coverage, statement coverage, cyclomatic complexity.
The main advantage of white box testing in database testing is that coding error are detected, so internal bugs in the database can be eliminated. The limitation of white box testing is that SQL statements are not covered.


The WHODATE approach for database testing

While generating test cases for database testing, the semantics of SQL statement need to be reflected in the test cases. For that purpose, a technique called WHite bOx Database Application TEchnique "(WHODATE)" is used. As shown in the figure, SQL statements are independently converted into GPL statements, followed by traditional white box testing to generate test cases which include SQL semantics.

Four stages of database testing

  • Set Fixture
  • Test run
  • Outcome verification
  • Tear down
A set fixture describes the initial state of the database before entering the testing. After setting fixtures, database behavior is tested for defined test cases. Depending on the outcome, test cases are either modified or kept as is. The "tear down" stage either results in terminating testing or continuing with other test cases.[5]
For successful database testing the following workflow executed by each single test is commonly executed:
1.   Clean up the database: If the testable data is already present in the database, the database needs to be emptied.
2.   Set up Fixture: A tool like PHPUnit will then iterate over fixtures and do insertions into the database.
3.   Run test, Verify outcome and then Tear down: After resetting the database to empty and listing the fixtures, the test is run and the output is verified. If the output is as expected, the tear down process follows, otherwise testing is repeated.

Some problems in database testing

1.   The setup for database testing is costly and complex to maintain because database systems are constantly changing with expected insert, delete and update operations.
2.   Extra overhead is involved in order to determine the state of the database transactions.
3.   After cleaning up the database, new test cases have to be designed.[citation needed]
4.   An SQL generator is needed to transform SQL statements in order to include the SQL semantic into database test cases.

Selenium Webdriver Latest jars released 2.43

Hello guys !!!
New Release came for Selenium Webdriver-2.43 yesterday (9-9-2014).

Selenium is going to give another release 2.43.1 in couple of day with some new feature.

These are some new changes in 2.43.0 lets have a look

Note- Please update the yous :


v2.43.0
======
WebDriver:

* Updating Native events to support Firefox 24, 31 and 32
* Add note on stale element checks and a WebElement represents a DOM element
* Upgrade third party dependency JavaScript-XPath to 0.1.12
* Fix example code: "using(-Chrome)DriverExecutable"
* Make event_firing_test.html pass in Firefox 24 ESR.
* Fix an error propagation bug when a command fails from bad inputs.
* Handle the case where a proxied element from PageFactory causes a FluentWait to timeout.
* Integrating the Microsoft Internet Explorer driver implementation
* Allow subclasses of HttpCommandExecutor to extend it at runtime.
* Handle the case where executeScript returns an HTMLDocument.
* IEDriver crashes in WaitUntilElementFocused() because of null pointer. Fixes issue #7577
* Deprecate the original RC interface in Selenium.
As part of Selenium 3.0, we shall be moving the original RC interface to a
legacy JAR that will be available as a separate download. As the first step
in this process, the original "Selenium" interface is being marked as
deprecated.
* Run FirefoxDriver tests with Buck.
* Bump timeout for tests since a suite is also a test.
* Run htmlunit-driver tests with Buck.
* Run the ignored tests printer with Buck.
* Get org.openqa.selenium.SmallTests building with Buck.
* Working around limitations in subpixel precision event handling.

The bug/limitation where browser supports subpixel precision for elements but not for dispatched events was found in both modern Chrome (http://crbug.com/396380) and Firefox (?) browsers.
(IE doesn't seem to be affected: before and including IE9 - no subpixel for elements and events; from ie10 - subpixel is supported for both elements and events).

This test was lucky so far (mostly?) and didn't hit this issue, until Chrome 37 that enabled subpixel text scaling by default.

This change makes *sure* elements have subpixel coordinates (if only browser supports'em) and then it makes sure this test doesn't fail because of that (while still testing selenium atoms).

While there, I moved asserts from event handlers into the normal test flow so jsunit can properly attribute assertion failures to specific test methods.
* Updating prebuilt libs for windows
* Re-add the rubyzip jar
* updating prebuilts for linux
* Updating to gecko 32
* Log formatter should be able to work with empty keys array. Fixes issue 7357
* Fixing infinite read from socket. Fixes issue 7814
* WDBS: safe check for window.localStorage
* Driver should operate cookies for the current frame, not the topmost one. Fixes issue 7799 in
Firefox
* Actually supporting promised Id for webdriver.WebElement.
* Adding more checks for JS functions removed from IE11. Fixes issue 7803
* Fixing use of deprecated API in httpclient
* Fixing use of deprecated API in guava
* Update Closure library to head and compiler to the latest release
* Implementing ability to use FirefoxDriver on a machine where localhost is not the first alias for
127.0.0.1. Fixes issue 3280
* Handle null and empty paths the same as /
* fixing maven build, adding reference to jetty-rc-repacked-5
* adding pom and info on uploading jetty-repacked-5 to maven central
* Adding checks for JS functions removed from IE11. Fixes issue 7780
* Deleting what appears to be unused deps.
* Add more options to the Builder API (every common, settable capability should be covered).
* Require calling Builder.usingServer(url) to use a remote server. If this is not called, the
builder will attempt to create a client locally, throwing an error if it can't (e.g. for IE).
* Add browser specific constructors to simplify creating a client without the Builder.
Fixes issue 7593
* Updating json-cpp lib and replacing mongoose web server with civetweb.
* Safari is flaky. Reducing timeout to fail faster when we're going to fail.
* Catch driver start-up failures.
* Add explicit API for configuring log prefs rather than forcing users to rely on
magic capability strings.
* Clean up internal Firefox logging API.
* Use LogLevelMapping to convert JSON wire protocol name to Level instance.
* Make the jettyMaxThreads parameter actually be effective
* Fix NullPointerException when File#listFiles() returns null. Fixes issue #1934
* Making WDBS.start command a no-op if it was instantiated with an already started driver. Fixes issue 3993
* Handling possible exception in stringification of window.location. Fixes issue 3908
* Modified IE driver server to more closely follow W3C spec

This commit includes a number of changes designed to bring the IE driver
into closer alignment with the W3C WebDriver specification. It provides
no functional changes to the driver, nor does it change any external-
facing API. The changes are:
* Changed webdriver::Server to examine the response from the newSession
command for the session ID rather than a two-stage process. The
webdriver::Server::DispatchCommand method now calls the
InitializeSession method directly when processing the newSession
command.
* Removed the now-obsolete webdriver::Server::CreateSession method.
* Added a Serialize/Deserialize method pair on the webdriver::Command
class (renaming the Populate method to Deserialize).
* Revamped the serialization of webdriver::Command to use 'name' instead
of 'command' for the command name.
* Added a session ID member to the webdriver::Command object.
* Modified the webdriver::Command object to no longer draw distinction
between parameters passed in as part of the URL substitution and those
passed in as part of the JSON payload in the body.
* Modified webdriver::CommandHandler::ExecuteInternal (and all subclass
implementations to use a single parameters map instead of the dual
URL tokens/JSON payload parameters maps used previously.
* Propagate webdriver_firefox_port preference to FirefoxDriver, was being ignored. Fixes issue 5172
* Adding a new selenium server option -logLongForm to log more details to the console. Fixes issue 6645
* Handling possible IllegalStateException while cleaning orphaned and timed out sessions. Fixes issue 6771
* Setting forwarded content for CommandListener afterCommand handler. Fixes issue 7443
* Fixing the list of extensions to search for an executable on Windows, and logging process startup
errors. Fixes issue 7514
* Setting layout.css.devPixelsPerPx to 1.0 if native events are enabled only. Fixes issue 7445
* BODY element is always shown/displayed.
related section in the W3C spec:
https://dvcs.w3.org/hg/webdriver/raw-file/default/webdriver-spec.html#determining-if-an-element-is-displayed
* Implementing switchToParentFrame support in atoms
* Setting HtmlUnit to emulate FF24 by default
* Updating HtmlUnit to 2.15
* Stop polluting the log with stacktraces. Fixes issue 7460
* Returning less specific platform info from firefox driver. Fixes issue 3354
* Adding driver info into TimeoutException thrown by WebDriverWait. Fixes issue 7429
* Implementing switchToParentFrame command for IE driver
* Adding URL endpoint for switchToParentFrame.

SAP TESTING

SAP:- Systems Applications and Products

SAP R/3 :- R stands for- Real-time 3- 3-tier Architecture

ERP stands for Enterprise Resource planning

ERP is a Business Management software-usually a suite of integrated applications-that a company can use to collect, store, manage and interpret data from many business activities.

It Includes:- Product planning, cost and development
Manufacturing or service delivery
Marketing and sales
Inventory management
Shipping and payment

--->SAP ERP or SAP ECC is enterprise resource planning software made by the German company SAP AG.

--->SAP ERP incorporates the key business functions of an organization.
ECC (ERP Central Component) is software version, released as ECC 5.0 in 2004.

--->SAP R/3 is an ERP software package implementation designed to coordinate all the key elements required to complete the business process.

--->SAP designed into different functional modules covering the typical functions of an organization.

How to do testing in sap R/3?

In any SAP Project testing can be happen in 3 phases. Unit testing happens in Dev server. Integration and User Acceptace Test happens in Quality Server.These all are done manually step by step. We have got standard SAP Test Scripts/prepares based on the Client/company/Project. Unit Testing: it can be tested in bits and pieces (Ex: Sales order Creation). Integration Testing: OTC Flow (Create Sales order to Invoice). User Acceptace done by the Client in "Q", if they are satisifed with the result they will give Sign-off for the project. There is another sort of testing so called Automated Regression Testing. that can be done by eCATT/IBM Rational Tools.

SAP Maual Testing (SAP SD, SAP MM, SAP FICO, SAP HR):
