Before we learn anything about ETL Testing its important to learn about Business Intelligence and Dataware. Let’s get started –
What is BI?
Business Intelligence is the process of collecting raw data or business data and turning it into information that is useful and more meaningful. The raw data is the records of the daily transaction of an organization such as interactions with customers, administration of finance, and management of employee and so on. These data’s will be used for “Reporting, Analysis, Data mining, Data quality and Interpretation, Predictive Analysis”.
What is Data Warehouse?
A data warehouse is a database that is designed for query and analysis rather than for transaction processing. The data warehouse is constructed by integrating the data from multiple heterogeneous sources.It enables the company or organization to consolidate data from several sources and separates analysis workload from transaction workload. Data is turned into high quality information to meet all enterprise reporting requirements for all levels of users.
What is ETL?
ETL stands for Extract-Transform-Load and it is a process of how data is loaded from the source system to the data warehouse. Data is extracted from an OLTP database, transformed to match the data warehouse schema and loaded into the data warehouse database. Many data warehouses also incorporate data from non-OLTP systems such as text files, legacy systems and spreadsheets.
Let see how it works
For example, there is a retail store which has different departments like sales, marketing, logistics etc. Each of them is handling the customer information independently, and the way they store that data is quite different. The sales department have stored it by customer’s name, while marketing department by customer id.
Now if they want to check the history of the customer and want to know what the different products he/she bought owing to different marketing campaigns; it would be very tedious.
The solution is to use a Datawarehouse to store information from different sources in a uniform structure using ETL. ETL can transform dissimilar data sets into an unified structure.Later use BI tools to derive meaningful insights and reports from this data.
The following diagram gives you the ROAD MAP of the ETL process

What is ETL Testing?
ETL testing is done to ensure that the data that has been loaded from a source to the destination after business transformation is accurate. It also involves the verification of data at various middle stages that are being used between source and destination. ETL stands for Extract-Transform-Load.
ETL Testing Process
Similar to other Testing Process, ETL also go through different phases. The different phases of ETL testing process is as follows

ETL testing is performed in five stages
1.Identifying data sources and requirements
3.Implement business logics and dimensional Modelling
4.Build and populate data

The shift towards microservices and modular applications makes testing more important and more challenging at the same time. You have to make sure that the microservices running in containers perform well and as intended, but you can no longer rely on conventional testing strategies to get the job done.
This is where new testing approaches are needed. Testing your microservices applications require the right approach, a suitable set of tools, and immense attention to details. This article will guide you through the process of testing your microservices and talk about the challenges you will have to overcome along the way. Let’s get started, shall we?
Traditionally, testing a monolith application meant configuring a test environment and setting up all of the application components in a way that matched the production environment. It took time to set up the testing environment, and there were a lot of complexities around the process.
Testing also requires the application to run in full. It is not possible to test monolith apps on a per-component basis, mainly because there is usually a base code that ties everything together, and the app is designed to run as a complete app to work properly.
Microservices running in containers offer one particular advantage: universal compatibility. You don’t have to match the testing environment with the deployment architecture exactly, and you can get away with testing individual components rather than the full app in some situations.
Of course, you will have to embrace the new cloud-native approach across the pipeline. Rather than creating critical dependencies between microservices, you need to treat each one as a semi-independent module.
The only monolith or centralized portion of the application is the database, but this too is an easy challenge to overcome. As long as you have a persistent database running on your test environment, you can perform tests at any time.
Keep in mind that there are additional things to focus on when testing microservices.
Test containers are the method of choice for many developers. Unlike monolith apps, which lets you use stubs and mocks for testing, microservices need to be tested in test containers. Many CI/CD pipelines actually integrate production microservices as part of the testing process.
As mentioned before, there are many ways to test microservices effectively, but the one approach that developers now use reliably is contract testing. Loosely coupled microservices can be tested in an effective and efficient way using contract testing, mainly because this testing approach focuses on contracts; in other words, it focuses on how components or microservices communicate with each other.
Syntax and semantics construct how components communicate with each other. By defining syntax and semantics in a standardized way and testing microservices based on their ability to generate the right message formats and meet behavioral expectations, you can rest assured knowing that the microservices will behave as intended when deployed.
It is easy to fall into the trap of making testing microservices complicated, but there are ways to avoid this problem. Testing microservices doesn’t have to be complicated at all when you have the right strategy in place.
There are several ways to test microservices too, including:
What’s important to note is the fact that these testing approaches allow for asynchronous testing. After all, asynchronous development is what makes developing microservices very appealing in the first place. By allowing for asynchronous testing, you can also make sure that components or microservices can be updated independently to one another.

Mobile application testing is the process of every application generated for handheld devices has to go through. This is to assure a specific level of the place before a request is delivered into the marketplace (app store/ play store). Mobile Application Testing is one of the software testing of applications on mobile devices to verify that the properties are running easily in terms of their operations, usability, functions, operations, and interaction. Looking for Mobile Testing Training in Chennai? Step into FITA, We are the best leading institution for Mobile Testing Course in Chennai.
There are two different approaches for Mobile Application testing based on their performance, they are:
• Manual testing
• Automated testing
Manual testing, as the title implies, is a human method, majorly concentrated on user activity. Evaluation and Report of the application’s security, functionality usability arranged through the factor of a user in an explorative method.
This assures that your statement lives up to a model of user-friendliness. This is a type of measurement that is frequently time-consuming as enthusiasts manage to get the opportunity to become identified.
Twenty percent of app testing must be arranged manually through the guidance of beta and alpha releases and remaining must be motorized.
let’s move on to automated mobile application testing.
Automated testing is secondary access to mobile application testing. In this method, an array of samples tests are structured. It should generally cover 80% of the testing process. The percentage is not required, but a common guideline developed in the software industry. Here is a list of test events that are frequently achieved through this critical method –
• Automate various tedious standard test cases.
• Automate test cases that can be quickly programmed
• Automate test cases that are impossible to perform manually
• Automate test cases for regularly used functionality
• Automate test cases with expected results
