Test Environment

What is the test environment?

The hardware and software components that make up the test environment enable us to carry out the test cases.

The developer gets to work writing the code as soon as we receive the request from the client.

After the development stage is over, the test server should have the application installed. You can use the URL, which may resemble something like this, to access that application:

Assume we have an application, database, hardware, and software configured on the ICICE Server.

To enable us run the test cases, the test environment includes a hardware configuration (RAM, Hard Drive, and Processor), software configuration (operating systems), and test console.
In the testing process, setting up the environment is a crucial step because, if you don’t configure it properly, the application may collapse, and the testing team won’t be able to start.Additionally, the environment and server name, such ICICE.com, might be the Production URL.
Since the database is secure, we are able to add, edit, and remove data from it.
n-number of end users (actual users) can access this server.

Software Server

We have four different kinds of servers here, which are as follows:
Production server
Development server
QA Main server
Staging server

Production Server
The production server is the server that houses the application development environment, hardware, and software. Users can access any website or online application using this core server.

Before deploying the application to the production server, we recommend debugging and testing it on the staging server, as the configurations of the two servers are comparable.

The production server’s features

This server is used by the end user, or actual user.
Since the production server holds actual user data, it is granted security.
system has a high configuration since it is utilized by n users.
You can access the production server using the production URL.

Once we have developed, tested, and ensured the stability of the application, we put it into the production environment.

Development server
Developers typically use it to write both new lines of code and bug fixes. We create and debug the software in a run-time environment that the development server provides.

QA Main server
Test engineers use it to perform various kinds of testing, and developers can use it to replicate the bugs. We will carry out the unit and integration testing on this server.

Test (Staging) server
Because the production server is heavily configured, we need to set up a similar server for conducting system testing.Therefore, we procure another server to verify the compatibility of the system.

We use a staging server to ensure that we have fixed the compatibility bugs in the application.

Before putting the program into the production server, this server helps us identify the performance, behavior, defects, and other software-related issues.

Process of test environment

We begin the first round of testing on the test server, which includes functional/unit and integration testing with standard settings, as soon as the customer provides the requirement and the developers complete the code.
The hardware and database in this instance are comparable to those of the production and staging servers, but all of the servers’ software should be the same.
We require a highly configured server known as the staging server for system testing. This server must resemble the production server in terms of software, hardware, and database.
We test the system on the staging server by utilizing the test URL.
We will turn over any bugs we uncover to the developers, who will address them.

We will only need two environments in a corporation, and they are as follows:
Dev Environment
Test environment
Instead of building a new database using the pre-existing development database, we will transfer the database from QA Main 1 to the staging server during the testing process in order to save time.
Afterward, transfer the application to the production server from the staging server (test server).

Why use a test environment that is identical to the server in use?

Since the user might run into some problems if we migrate the application from minimal configuration to production. We conduct one round of end-to-end (system) testing in a setting that is comparable to the production environment in order to prevent this.

The reasons why we require a test environment that is comparable to the production server are as follows:

The software should be similar to the production
The DB should be similar.
The OS should be similar.

The web server need to be comparable.
An analogous application server should be used.
Hardware need to resemble industrial equipment.

The production server’s hardware configuration should be emulated.
For instance, the test server ought to be the ICICE server if the production server is the ICICE server.

Hardware and setup must be comparable yet differ in capacity, that is, in CPU count.
The information ought to resemble the output.

We ought to generate data that is comparable to the output.
We can add n number of items to the database in a real-time setting, however we are unable to manually add n number of entries during testing. Thus, we create a test script that generates thousands of entries for testing purposes.
