This is the hardest thing as a developer I found, as there is no official documentation available to integrate the CCAvenue. Also, you will not find any tutorial or blog from which you can do the implementation.

So, in this tutorial, we are going to cover how we can integrate the CCAvenue payment gateway with Laravel.

web.php

Route::post('purchase', [CCAvenueController::class, purchaseSubscription']);

CCAvenueController.php

public function purchaseSubscription(Request $request)
{
    $input = $request->all();

    $input['amount'] = $data['grandTotal'];
    $input['order_id'] = "123XSDDD456";
    $input['currency'] = "INR";
    $input['redirect_url'] = route('cc-response');
    $input['cancel_url'] = route('cc-response');
    $input['language'] = "EN";
    $input['merchant_id'] = "your-merchant-id";

    $merchant_data = "";

    $working_key = config('cc-avenue.working_key'); //Shared by CCAVENUES
    $access_code = config('cc-avenue.access_code'); //Shared by CCAVENUES

    $input['merchant_param1'] = "some-custom-inputs"; // optional parameter
    $input['merchant_param2'] = "some-custom-inputs"; // optional parameter
    $input['merchant_param3'] = "some-custom-inputs"; // optional parameter
    $input['merchant_param4'] = "some-custom-inputs"; // optional parameter
    $input['merchant_param5'] = "some-custom-inputs"; // optional parameter
    foreach ($input as $key => $value) {
        $merchant_data .= $key . '=' . $value . '&';
    }

    $encrypted_data = $this->encryptCC($merchant_data, $working_key);
    $url = config('cc-avenue.url') . '/transaction/transaction.do?command=initiateTransaction&encRequest=' . $encrypted_data . '&access_code=' . $access_code;

    return redirect($url);
}

Manage Callback

public function ccResponse(Request $request)
{
    try {
        $workingKey = config('cc-avenue.working_key'); //Working Key should be provided here.
        $encResponse = $_POST["encResp"];

        $rcvdString = $this->decryptCC($encResponse, $workingKey);        //Crypto Decryption used as per the specified working key.
        $order_status = "";
        $decryptValues = explode('&', $rcvdString);
        $dataSize = sizeof($decryptValues);
}

Other Encryption functions

public function encryptCC($plainText, $key)
{
    $key = $this->hextobin(md5($key));
    $initVector = pack("C*", 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f);
    $openMode = openssl_encrypt($plainText, 'AES-128-CBC', $key, OPENSSL_RAW_DATA, $initVector);
    $encryptedText = bin2hex($openMode);
    return $encryptedText;
}

public function decryptCC($encryptedText, $key)
{
    $key = $this->hextobin(md5($key));
    $initVector = pack("C*", 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f);
    $encryptedText = $this->hextobin($encryptedText);
    $decryptedText = openssl_decrypt($encryptedText, 'AES-128-CBC', $key, OPENSSL_RAW_DATA, $initVector);
    return $decryptedText;
}

public function pkcs5_padCC($plainText, $blockSize)
{
    $pad = $blockSize - (strlen($plainText) % $blockSize);
    return $plainText . str_repeat(chr($pad), $pad);
}

public function hextobin($hexString)
{
    $length = strlen($hexString);
    $binString = "";
    $count = 0;
    while ($count < $length) {
        $subString = substr($hexString, $count, 2);
        $packedString = pack("H*", $subString);
        if ($count == 0) {
            $binString = $packedString;
        } else {
            $binString .= $packedString;
        }

        $count += 2;
    }
    return $binString;
}

That's it.

So that is how you can integrate the CCAvenue Payment Gateway with Laravel.

Adobe Photoshop has long been the go-to software for graphic designers, offering powerful tools and endless creative possibilities. Photoshop has taken a huge step ahead with the use of artificial intelligence (AI) technology, allowing designers to improve their productivity, automate repetitive operations, and generate amazing outcomes more effectively than ever before. In this blog post, we will explore the AI-based tools in Adobe Photoshop that are revolutionizing the field of graphic design.

Generative Fill:

Generative Fill is an AI-powered tool in Adobe Photoshop that uses machine learning techniques to automatically create complicated and visually appealing patterns and textures. Generative Fill creates new designs using rich details, organic shapes, and appealing styles by analysing existing visual elements or utilising a set of established characteristics. This technology allows designers to quickly explore and experiment with an array of artistic possibilities without the need for manual design or complex work flows.

Open the image you want to manipulate in Photoshop beta. Use any selection tool to choose the specific area you want to apply the Generative Fill to. Click on the "Generative Fill" button located in the small toolbar that appears. In the prompt box, type your desired instructions for the tool or leave it blank. Once satisfied, click "Generate" to initiate the Generative Fill process. Wait for a few seconds to a few minutes, depending on the complexity of the prompt, as Generative Fill completes your request. The AI will provide you with three variations to choose from. Select the option you like best to apply it. The changes will be applied to a separate layer, preserving your original image on the base layer.

Content-Aware Fill:

One of the standout AI-powered features in Photoshop is Content-Aware Fill. This tool analyzes the content surrounding a selected area and automatically fills it in a way that seamlessly blends with the surrounding elements. Whether removing unwanted objects or extending backgrounds, Content-Aware Fill saves designers valuable time and effort by intelligently generating realistic replacements.

Select an object in your photo, go to Edit, and choose Content-Aware Fill. You’ll be able to refine your selection further and see a preview of how the fill is going to work. You can specify areas of the image Photoshop should use to fill in the background once it removes the object.

Neural Filters:

Neural Filters is a set of AI-powered filters in Photoshop that leverages machine learning algorithms to apply complex transformations to images. These filters enable designers to achieve artistic effects, retouch portraits, adjust facial expressions, and enhance details with just a few clicks. From the Style Transfer filter to the Smart Portrait filter, Neural Filters offer a wide range of creative options to elevate your designs.

To use them, go to Filter in the main navigation bar and then click on Neural Filters. You’ll be able to choose from a wide range of actions, such as adding depth to your images and smoothing the skin on people’s faces. Each filter comes with its own set of options, so you can tweak them to make them more or less aggressive, depending on what you want your final photo to look like.

Sky Replacement:

The Sky Replacement feature in Photoshop utilizes AI algorithms to automatically detect and replace the sky in an image while preserving other elements like foreground objects and lighting conditions. Designers can choose from a library of preloaded skies or add their own, transforming the mood and atmosphere of a scene in an instant. This tool simplifies the process of creating captivating visuals with dramatic sky effects.

Open an image, go to Edit, and then Sky Replacement to make alterations. You can drop in one of the program’s pre-sets or load your own, as well as tweak the sky’s temperature and brightness, and make adjustments to the foreground to help it match the lighting.

Select Subject and Object Selection:

Selecting intricate subjects or objects within an image can be a time-consuming task. Adobe Photoshop's AI-based Select Subject and Object Selection tools come to the rescue. These tools utilize advanced machine learning algorithms to intelligently identify and isolate subjects or objects, allowing designers to make precise selections quickly. This feature greatly enhances the efficiency of various design workflows, such as compositing and retouching.

Stripe Connect is the fastest way to integrate payment into your marketplace.

In this tutorial we are going to integrate the stripe connect with Laravel.

To integrate the stripe connect you must need the stripe secret and the stripe key. You can get that credentials from your Stripe account.

So let's start integrating...

Installation

composer require srmklive/paypal:~2.0

Onboard the seller using Stripe connect

Define the route for onboarding the seller.

  Route::get('onboard-seller', [StripeController::class, 'onboard']);

Now on StripeController.php write the code for the onboarding link.

use Stripe\Stripe;
use Stripe\Account;
use App\Models\User;
use Stripe\AccountLink;

public function onBoard()
{
    $user = Auth::user();

    /** @var User $user */
    if (empty($user->stripe_on_boarding_completed_at)) {
        Stripe::setApiKey(stripeKey());

        if (empty($user->stripe_connect_id)) {
            /** @var Account $account */
            $account = Account::create([
                'type'         => 'express',
                'email'        => $user->email,
                'country'      => 'US',
                'capabilities' => [
                    'card_payments' => ['requested' => true],
                    'transfers'     => ['requested' => true],
                ],
                'settings'     => [
                    'payouts' => [
                        'schedule' => [
                            'interval' => 'manual',
                        ],
                    ],
                ],
            ]);

            $user->stripe_connect_id = $account->id;
            $user->save();
        }

        $user->fresh();

        $onBoardLink = AccountLink::create([
            'account'     => $user->stripe_connect_id,
            'refresh_url' => route('organization.dashboard'),
            'return_url'  => route('stripe.onboard-result', Crypt::encrypt($user->stripe_connect_id)),
            'type'        => 'account_onboarding',
        ]);

        return redirect($onBoardLink->url);
    }


    $loginLink = $this->stripeClient->accounts->createLoginLink($user->stripe_connect_id, []);

    return redirect($loginLink->url);
}

Please note that you have to generate routes for return and cancel URLs.

Once a merchant is successfully onboarded stripe will again redirect him to the return_url

Below you can find the code in which we managed the success callback.

public function onBoardResult($encodedToken)
{
    /** @var User $user */
    $user = User::whereStripeConnectId(Crypt::decrypt($encodedToken))->firstOrFail();

    $user->stripe_on_boarding_completed_at = Carbon::now();
    $user->save();

    return redirect(route('dashboard'));
}

In this article, We will see the difference between regression testing vs retesting.

The concepts of regression testing and retesting are generally confused within the field of test automation. They sound similar and they have correlations too.

The main difference is that regression testing is designed to test or verify for bugs you don’t expect to be there. Retesting is designed to test or verify for bugs you do expect to be there.

What is Regression Testing?

Regression testing is a type of software testing executed to check whether a code change has not critically disturbed the current functions & features of an application/software, what does it mean that the point of regression testing is to make sure that new updates or features added/release to software don’t break any previously released updates or features or functions.

What is Retesting?

Retesting is done to ensure that the bug is fixed and even if failed functionality is working fine or not, this is a kind of verification process followed in the testing field for the fixed bugs. Most of the testers having confused with Regression and Retesting.

Boost Customer Satisfaction, Find out Hidden Bugs In Your Software

Generally, testers find bugs while testing the software application or website and assign them to the developers to fix them. Then the developers fix the bug and assign it back to the testers/QA for verification. This continuous process is called Retesting.

Difference between Regression Testing and Retesting.

We could say that regression testing is a type of retesting. Retesting really means testing something again. And when we are regression testing, we are testing something that we have tested numerous times before.

But determining what the two have in common or similar might confuse more than it will help. So, for the well-being of clarity, below is an overview of the key differences.

Regression Testing Vs Retesting

Regression Testing	Retesting
Regression Testing is carried out to establish whether a recent program or code change has not negatively affected existing features.	Re-testing is carried out to establish the test cases that failed in the final execution are passing after the defects are fixed.
The purpose of Regression Testing is that new code fixes should not have any side effects on existing functionalities.	Re-testing is performed on the basis of the defect fixes.
Regression Testing can be carried out parallel with Re-testing, based on the project and availability of resources.	Retesting is carried out before regression testing because the priority of re-testing is higher than regression testing.
Defect verification is not part of regression testing.	Defect verification is part of re-testing.
Regression testing is known as genetic testing.	Re-testing is planned to test.
Regression testing is executed for passed test cases.	Retesting is executed for failed test cases only.
Regression testing checks for unexpected side effects.	Re-testing ensures that the original fault has been corrected.
Regression testing is only done when there are any modifications or fixes become mandatory in an existing project.	Re-testing executes a defect with the same data in the same environment with different inputs with a new build.
We can do automation for regression testing; Manual testing could be time-consuming and expensive.	We can’t automate the test cases for retesting.
Test cases for regression testing can be captured from the functional specification, user manuals and tutorials, and defect reports in regard to corrected problems.	Test cases for retesting cannot be captured before starting testing.

Conclusion:

In case you are still confused, it may be easier to think of retesting as checking to see whether the bug actually fixed and regression testing as whether you created any new bugs with your fix. While you may identify regression issues during a retest, they are in fact separate and should be treated as distinct forms of testing.
