Chrome for Testing: Browser Automation made easy

Chrome for Testing


Introduction

Google Chrome for Testing is a new Chrome flavor that specifically targets web app testing and automation use cases.

Browser and Driver Setup and Maintenance

Setting up a browser testing environment is a difficult task, and it needs more effort to keep the browser and the chrome driver up-to-date and it is a top web developer / automation engineer's pain point

The Auto-Update

One of Chrome’s most notable features is its ability to auto-update. This helps the users to keep their browsers up-to-date with the latest upgrades and be safe when they are online

As a developer / automation engineer, running a suite of end-to-end tests requires the below aspects to be taken care of

  • You want consistent, reproducible results across repeated test runs—but this may not happen if the browser executable or binary decides to update itself in between two runs.
  • You want to pin a specific browser version and check that version number into your source code repository, so that you can check out old commits and branches and re-run the tests against the browser binary from that point in time.

The process of a browser that auto-updates creates compatibitlity with webdriver and there needs to be a manual intervention to address this.

Versioned browser binaries

Google intentionally doesn’t make versioned Chrome downloads available, since users shouldn’t have to care about version numbers—they should always get updated to the latest version as soon as possible. This is great for users, but painful for developers needing to reproduce a bug report in an older Chrome version

Due to the manual intervention and addressing of the version issue, there are flaws.

  • First, these Chromium binaries are not reliably available across all platforms.
  • Second, they are built and published separately from the Chrome release process, making it impossible to map their versions back to real user-facing Chrome releases.
  • Third, Chromium is different from Chrome

Chrome for Testing

Designed to solve these problems, Chrome for Testing is a dedicated flavor of Chrome targeting the testing use case, without auto-update, integrated into the Chrome release process, made available for every Chrome release. A versioned binary that’s as close to regular Chrome as possible without negatively affecting the testing use case.

The difficulties we previously mentioned around finding a matching Chrome and ChromeDriver binary can be completely eliminated by integrating the ChromeDriver release process into the Chrome for Testing infrastructure. In addition to solving this user-facing pain point, this also aligns ChromeDriver releases with Chrome’s, and eliminates the manual ChromeDriver release process.

Conclusion

The release of chrome for testing is a big boon for the developers and the automation engineers that helps in fixing the chrome and driver compatibilty across upgrades. Please read through the below link to learn more and to use the latest commands from google team Chrome Blog
Happy & Peaceful Testing !!!

User Authentication schemes in a Multi-Tenant SaaS Application

User Authentication in Multi-Tenant SaaS Apps Introduction We will cover few scenarios that we can follow to perform the user authentication in a Multi-Tenant SaaS application. Scenario 1 - Global Users Authentication with Tenancy and Tenant forwarding In this scheme, we have the SaaS Provider Authentication gateway that takes care of Authentication of the users by performing the following steps Tenant Identification User Authentication User Authorization Forwarding the user to the tenant application / tenant pages in the SaaS App This demands that the SaaS provider authentication gateway be a scalable microservice that can take care of the load across all tenants. The database partitioning (horizontal or other means) is left upto the SaaS provider Service. Scenario 2 - Global Tenant Identification and User Authentication forwarding   In the above scenario, the tenant identification happens on part of the SaaS provider Tenant Identification gateway.

Implementing Row Level Security [RLS] for a Multi-Tenant SaaS Application

Row Level Security The need for row level security stems from the demand for fine-grained security to the data. As the applications are generating vast amounts of data by the day. Application developers are in need of making sure that the data is accessible to the right audience based on the right access level settings. Even today, whenever an application was built, the application development team used to spend a lot of time researching the approach, implementing multiple tables multiple logics 25 queries to add filters to manage the data security for every query that gets transferred from the end user request to the application database. This approach requires a lot of thought process, testing and security review because the queries needs to be intercepted, updated and the data retrieval to be validated to make sure the end-users see only the data that they are entitled to. Implementation With the advent of of row level security feature being rolled out in main d

Async implementation in Blazor

Step-by-Step Guide to Achieving Async Flows in Blazor: 1. Understanding Asynchronous Programming: Before delving into Blazor-specific async flows, it's crucial to understand asynchronous programming concepts like async and await . Asynchronous operations help improve the responsiveness of your UI by not blocking the main thread. 2. Blazor Component Lifecycle: Blazor components have their lifecycle methods. The OnInitializedAsync , OnParametersSetAsync , and OnAfterRenderAsync methods allow you to implement asynchronous operations during various stages of a component's lifecycle. 3. Asynchronous API Calls: Performing asynchronous API calls is a common scenario in web applications. You can use HttpClient to make HTTP requests asynchronously. For example, fetching data from a remote server: @page "/fetchdata" @inject HttpClient Http @ if (forecasts == null ) { <p> < em > Loading... </ em > </ p > } else { <table>
