What is End-to-End Testing in reality?

End-to-End Testing is a complicated term, including various activities types, determining the way how an application is meant to be run. We talk about a severely standardised software testing methodology, representing all possible instruments for accurate functionality and performance checks, equally supporting any scale software.

Generally, End-to-End Testing definition lies somewhere between a strictly planned algorithm and a completely creative task, involving human fantasy to the process. Checking mechanism is adapted during a complete software development life cycle, embracing a full-stack low-tier applications needs.

To say briefly, the E2E approach tests various software algorithms, which have possibilities to be activated by the end user.

Representative End to End Testing Example from experienced personnel


Let’s model a simple E2E Test scenario, which predicts a typical user behaviour on an ordinary eCommerce site. That’s an easy way to catch an End-to-End logic:

  • Log into an e-commerce site. First step, nothing special here.
  • Use the universal search bar for finding the desired product for purchase. As per statistics, a universal search bar attracts way more attention than actual website contents as it simplifies surfing process.
  • Use pagination to navigate onto a second page through search results. It happens very often that user is not satisfied with the first page results, so he goes further.
  • Click on a specific item to open the product description page. Once a desired item is found, user observes its informational card.
  • Add the product to the shopping cart. Being satisfied with needed item characteristics, user commences purchase procedure.
  • Checkout to the shopping cart. User proceeds to the next purchase stage.
  • Make payment by selecting the specific payment option. User makes transaction by protected eCommerce means.
  • Sign out of the application. End of the agreement and session.

Each behavioural stage is checked to see if algorithms work properly enough or not.

Finally, Why are End-to-End Tests Important?

E2E Testing usually helps to provide a thorough complete exploration of software functionality from the beginning to the end, following each possible usage scenario. A diligent development team runs different mechanics, e.g. regression and functionality algorithms to ensure in which way the application responds to user requests.

As a rule, End-to-End test scenarios establish understanding between stakeholders and users, eventually eliminating bugs which occur during substandard product usage or unpredictable situations, which may take place.

Alfee cares about customers and their client base, so check is performed perfectly by thrillingly educated personnel.

Main Purpose of End-to-End Test environment commitment

Before falling into procedure flow, we need to establish primary objectives of E2E Integration Testing, because no business is successful without proper goals setting. Fixed chain of actions reinforces effective mechanisms, allowing to accumulate necessary practices.

At the time of E2E Testing listed below objectives have to be met surely:

  1. 01
    Ensuring the main product is well positioned in relation to each substitute module.
  2. 02
    The sub-systems also include manufactured by third-party companies, not by your side.
  3. 03
    Checking on the flows coming from provenance systems to intended ones.
  4. 04
    Validating all the requirements looking from end user point of view.
  5. 05
    Identifying heterogeneous defects coming from surrounding spaces.

What is End-to-End Testing in Software Test coverage actually?

Usually E2E Testing stays alongside system testing as well. But consider that even IT software veterans get completely disoriented, filled with huge advantages of both mechanisms, which makes a choice completely unpredictable if you don’t know special secrets.

Let us begin with system technique explanations, as it is more convenient to announce required information. System technique is performed for an integrated software validation. Although End-to-End Testing sets the same approach, indicated mechanisms differ by final targets. You may initiate a system verification only after all program modules one-by-one inspection. Same with this, module-based procedure guarantees a seamless structural elements integration. Another one condition which causes system verification initiation is a pseudo-environment presence.

This article also mentions other E2E Testing benefits, e.g. software is qualified for End-to-End test only after passing the system check successfully.

Let us compare the E2E test with the system one.

E2E Testing as a System Testing part in details

Below you may see a table with comparative characteristics of both checkings mechanics, designed specially to mitigate understanding level, illustrating common laws spread to each single case.

E2E Testing explanatory note

  • Testing against specific business requirements means dedication to commercial supertasks.
  • Includes infrastructure level testing as it goes deeper to the organisational field regulating each process separately and in common.
  • Performed once integration and data integrity testing is qualified certifying a particular application withstands against marketplace turbulences with dignity.
  • Requires strong knowledge of user workflows to catch a psychology correctly and create a human-oriented product.
  • Testing front-end, backed & middle-tier system especially paying attention to users' demand.

System Testing explanatory note

  • Testing against specific technical requirements means dedication to domestic application algorithms which ignores financial aspect.
  • Includes functional and non-functional testing which still occupy important positions in software building, as they reveal possible usage problems which may occur later.
  • Performed towards the end of SDLC to ensure that applications meet technical requirements in the full scope.
  • Requires strong knowledge of the developed product to deliver smooth algorithms performance.
  • Scrutinised to find unexpected results fixing on exact code problems.

Some Critical Challenges Caused by E2E Testing Procedure

Properly acquired Quality Assurance team works as a gatekeeper for the software being built. As a rule, a diligent QA team develops an E2E test plan right after particular requirements discovery.

Anyway, let us name some obstacles preventing from success:

  1. 01
    QA engineers possibly will see a learning deterioration during programming at first days. Especially with constant waving of technical requirements. Such a tactics prevents specialists from the correct price evaluation resulting in E2E test cases effectiveness reducement.
  2. 02
    Usually E2E tests disturb enough with their difficulty, so manual technique may not be fully applicable here.
  3. 03
    It’s better to realise End-to-End cases in a production environment rather than natural, but it fully depends on software nature. Sometimes if it is not possible to arrange verification during the development process, imitate later production conditions as close to the sample as possible.

Various Methods Used in End-to-End Testing

E2E Testing might be performed in two completely different ways. It all lies on what exact software type is being produced. Different minor conditions should also be considered if they influence the development process and then, as a consequence, a verification result. Let us explain more below:

Horizontal Method explanatory note

The Horizontal Method is the most widespread concerning E2E Testing approach. Same as the mechanics name says, an indicated method lasts from beginning till completion of the development passing through it horizontally. The biggest profit regarding such a method is that it could be deployed fully within a single Enterprise Resource Planning (ERP) application.

Vertical Method explanatory note

This one method compared to horizontal is a little bit more sophisticated but at the same time very useful. End-to-End tests corresponding to selected models are performed in layers, using a sequential or hierarchical organisation. To arrange the procedure correctly, you must verify the software accurately from the beginning to the end. This software testing method reveals critical components shortcomings as well.

E2E Automation Scripts

unit testing process / modern software systems

Honestly, automated E2E tests bring way more profits than manual ones as they come easier with cost consciousness. Of course, building automated E2E tests is connected with certain difficulties and risks, though you will get more advantages.

From the business position, there is one numerical indicator, defining everything in brief: ROI or simply the Rate of Investments. It describes funds allocation effectiveness. For this reason a professional QA team should be hired to ensure that financial flows go ahead and correctly, without enforcing too many mistakes, especially connected with digitised environments.

Arranging End-to-End tests automation frees even more money which might be used somewhere else, but not paying for the manual job that could be done faster & cheaper. Beyond all this, AI-based features provided exclusively by Alfee will surprise each client who values his time and money, as brand new technologies celebrate a victory of pure mind defeating entropy laws. Evaluating with Artificial Intelligence techniques brings ground-hitting results as well.

Estimating E2E Test Cases Performance Quality

As every procedure held, E2E automated or manual tests as well show some definite effectiveness level we should establish. Hire a highly professional QA experts team to figure out how usefully procedures were done considering your business model and targets set.

Such mechanics are used usually:

  • Test Case Preparation. It is your responsibility to check if the End-to-End test suite contains correctly picked cases, because this is a basement of forthcoming adventures.
  • Availability of Test Environment. For E2E test suite it useful to be launched in different environments to establish application reactions thoroughly.
  • Test Case Execution and Reporting. Good stakeholders are informed stakeholders, so in your interests to generate percentage-based reports periodically to show them how things are going, especially considering number of checks performed, passed and failed.
  • Defects Tracking and Detailing. One of the main effectiveness characteristics is a bug quantity found. Hold this procedure regularly with further bugs elimination priority, and you will get a perfectly effective software with useful updates.

E2E Testing Abilities and how it influences a Software Application

E2E Testing shows complete irreplaceability, as developers monitor certain software functioning results, and stakeholders completely imagine what processes are going under the shell. Good E2E tests completely terminate ignorance overflow.

  1. 01
    The first and foremost benefit concerns reduced bugs amount, so they don’t remain in the release version, sufficiently improving a user experience.
  2. 02
    Employing an automation tool is another of useful benefits connected with sufficient time reduction. This procedure might also be integrated with your CI/CD mechanics easily.
  3. 03
    There is no better way to expand procedure scale than applying an E2E approach. It checks if all software dependencies interact correctly, especially third-party segments.
  4. 04
    The outcome of these tests affects users the most, so there will be no need for them to contact your 24/7 support.
  5. 05
    If you have a well-designed E2E test suite, then it might be run effectively by other software stakeholders as well. For example, UATs with software owners may effectively use such procedures in critical decisions making which sufficiently increases business effectiveness. Same with this they can adapt it in other software-related measurements.

Making a No-Code Automation Tool for E2E Tests more valuable

We already said before that automating end-to-end tests brings benefits which become too crucial to remain overboard. But unfortunately the latest statistics indicate that the automation process affected only 30% of mechanics in 2022. It is caused mostly by such a transition complicity and deteriorated results stability due to large dependency numbers all over the project. Anyway, Alfee is an honoured specialist in the End-to-End Testing field, showing unbelievable results where others may only nod their heads. We propose a unique instrument that makes E2E automated tests easy even for those gentlemen who are not familiar with the programming science.

We turned E2E tests construction into a highly cost-effective solution which allows us to reduce financial spendings and increase development effectiveness dramatically. Moreover, such mechanics deeply engages high-level programming languages so that even completely technically unaware persons, especially businessmen and stakeholders, are able to read and understand what is going on in the code. And finally, QA and Dev team would be facilitated directly implying top-notch practices wherever demanded.

Logical Conclusions

A true E2E Testing procedure is famous for a non-banal approach concerning all development cases, especially aftermath stages, where severe monitoring is needed to detect mistakes in ample time. Being performed correctly, they stipulate immense software-constructing results, reinforcing its notability on marketplaces due to positive feedback. It renders assistance uninterruptedly, becoming a universal irreplaceable tool in the stakeholders hands.

Amplifying E2E dashboards usage, developers prioritise their creative input into the working system, controlling an outcoming informational flow. Same with this, such a testing approach delivers a secure software solution with no mistakes flows included.

Constructing fully-flinged verification instruments with the help of top-grade no-code automation tool vitalises an application lifecycle durability with complete customers’ satisfaction. We at Alfee proudly insist that such mechanics implies terrifically equated software development scope, prioritising clients needs all over the process.
