Testing(Manual or Automated) depends a lot on the test data being used. In a fast paced dynamic agile development quality of data being used for testing is paramount for success.
This document discusses data quality testing. It begins by defining data quality and listing its key dimensions such as accuracy, consistency, completeness and timeliness. It then notes common business problems caused by poor data quality and the benefits of improving data quality. Key aspects of data quality testing covered include planning, design, execution, monitoring and challenges. Best practices emphasized include understanding the business, planning for data quality early, being proactive about data growth and thoroughly understanding the data.
According to our customer surveys and confirmed by industry statistics, manual testers spend 50-70% of their effort on finding and preparing appropriate test data. Considering the fact that manual testing still accounts for 80+% of test operation efforts, up to half (!) of the overall testing effort goes into dealing with test data.
Find out how Tosca Testsuite can help you to lower the maintenance effort of your test data and operating costs of your test environment while building an efficient test data management strategy.

Democratizing Data Quality Through a Centralized PlatformDatabricks
Bad data leads to bad decisions and broken customer experiences. Organizations depend on complete and accurate data to power their business, maintain efficiency, and uphold customer trust. With thousands of datasets and pipelines running, how do we ensure that all data meets quality standards, and that expectations are clear between producers and consumers? Investing in shared, flexible components and practices for monitoring data health is crucial for a complex data organization to rapidly and effectively scale.
At Zillow, we built a centralized platform to meet our data quality needs across stakeholders. The platform is accessible to engineers, scientists, and analysts, and seamlessly integrates with existing data pipelines and data discovery tools. In this presentation, we will provide an overview of our platform’s capabilities, including:
Giving producers and consumers the ability to define and view data quality expectations using a self-service onboarding portal
Performing data quality validations using libraries built to work with spark
Dynamically generating pipelines that can be abstracted away from users
Flagging data that doesn’t meet quality standards at the earliest stage and giving producers the opportunity to resolve issues before use by downstream consumers
Exposing data quality metrics alongside each dataset to provide producers and consumers with a comprehensive picture of health over time
Most companies do not think of data when they start out, let alone the quality of that data. With the proliferation of data and the usages of that data, organizations are compelled to focus more and more on data and their quality.

1) The document discusses an approach for managing test data to support regression testing of data intensive applications. It involves maintaining a managed test data environment separate from the integrated test environment.
2) Progression testing is done first in the integrated environment to validate changes before adding test cases to the regression suite. Then automated regression testing is done using the managed test data environment, with test scripts independent of application logic.
3) Periodic refreshes of test data from production help keep the managed environment in sync with evolving business and technical changes. This approach optimizes regression execution time while focusing QA efforts on domain knowledge rather than data handling.
While the companies are making the use of information oceans and derive profits from the data they store; at the same time they suffer from it. It is obvious that no company can cope with data growth by just increasing their hardware capacity. Companies need to find out smart solutions for this inevitable growth.
When we degrade the subject into testing, we observe that IT organizations are deeply focusing on the collection and organization of data for their testing processes. The ability to control this process and use test data has become the key competitive advantage for these organizations because benefits of such mechanisms will worth against their tradeoffs. Ultimately, test data management plays a vital role in any software development project and unstructured processes may lead organizations to;
•Do inadequate testing (poor quality of product)
•Be unresponsive (increased time-to-market)
•Do redundant operations and rework (increased costs)
•Be non-compliant with regulatory norms (especially on data confidentiality and usage)
No matter which approach you choose to eliminate the challenges of this important subject, test data management; basic requirements for you to be successful are; combination of good test cases and test data, along with the proper usage of tools to help you automating extraction, transformation and governance of the data being used.

The document discusses test data management and creating a mindmap to help organize test data management tasks. It outlines best practices for test data management, including identifying data sources, extracting and transforming data, provisioning data for testing, and maintaining test data over time. Creating a mindmap helps visualize the important tasks, reduce effort spent on test data preparation, and leads to improved testing quality through more accurate test data.
This document discusses testing approaches for a data analysis framework called PPA Framework. It begins by describing PPA Framework's process flow, which involves data collection, processing, transformation, and analysis/visualization. It emphasizes the need for testing to ensure the framework's validity and accuracy. It then contrasts traditional software testing approaches with those more suitable for data analytics platforms, which involve testing data quality, preprocessing, model accuracy, and visualization. Key testing thoughts discussed include unit testing of components, integration testing between modules, data validation testing, and accuracy/precision testing using known inputs and expected outcomes. The goal is to increase confidence in the framework's reliability and maintain records of its performance over time.

Test data management
1. TEST DATA MANAGEMENT
The need for Continuous testing and Integration is well acknowledged
across the industry today in order to fully embrace the agile
methodology. This requires a complete shift to an extremely dynamic
and Flexible development and testing process. For this access to Quality
test data is the key to success.
The Success factors also include a comprehensive test coverage leading to early detection of Defects. A
strong test data strategy to overcome some of the challenges:
Lack of Specific data sets to test.
Not knowing where to look for the data/ not having appropriate access to the data.
Effort wastage in coordination, operational inefficiencies.
Introduction
Managing Test Data in Multiple environments(Non Production) is essential to enhance the quality of
testing and optimizing effort in following ways:
Functional Testing:
An effective (Positive/ negative) functional test with appropriate test data helps in:
Finding defects early.
Focus on functional and Regression tests and not on steps required to reach the desired
test state.
Performance Testing:
For applications where big data is involved, and performance is paramount, a robust, strong automated
test data strategy is required. For sustained performance tests, test data must comprise of:
Stability
Load
Baseline
Services Virtualization:
Realistic test data is required to simulate a live service behavior in an integrated fashion.
Subset of Production data helps in emulating end user behavior during beta releases/ UAT.
2. Essential Steps for a Streamlined Test Data management
Data requirement Analysis:
Test data is predominantly created based on the Test Requirements. However, the complete analysis of
data must consider the following
Systems: Systems involved in all of the testing phases.
Formats: Format of data which may be needed by different systems (Normalized, Raw, Json, Xls
etc.) or different testing requirements (Negative, Positive, boundary values etc.)
Rules: Different rules may be applied to data at different stages of testing or location or type of
data. For example: A service test may require data in raw format, however for doing a system
test the requirement may be of a normalized format.
Data Setup/Provisioning:
There can be different approaches for creation of a realistic, referentially correct/intact test data.
Subset of Production data: This kind of data set is most accurate and can be easily created
without adding a lot of administrative costs or challenges. These data sets are small enough to
accommodate model changes but large enough to simulate production like behavior. The only
in this approach is when sensitive data such as personal information of customer or encrypted
data is involved.
Automated Data creation: In absence of any kind of production data, for effective testing,
automated data generation jobs can be created which creates a large data set for both
functional and non-functional testing. This data set is created to force error and boundary
conditions.
Data Restrictions:
Data restrictions can be due to Regulations, Compliance, or sensitive client/customer data. Capabilities
must be developed to de-mask such confidential data and provide a real look and feel. For example: In a
cloud based testing model sensitive client information must not be shared.
Test Data Administration:
Golden Copy: Creating a new copy of test data at each phase of testing or release will lead to a
lot of effort consumption and may bear different results. Hence it is always a good idea to create
a golden copy of reference data and provision a copy/ subset of the same depending on the test
requirements.
3. Maintenance: Data maintenance is necessity at periodic intervals. This is required due to
application design changes, Data model changes or plugging gaps identified from earlier test
cycles.
Data Refresh: This is often required to reset the data source of test data environment for
multiple rounds of testing as during testing the test data may be altered or exhausted.
In a nutshell the effectiveness of test data management is critical for successful validation of any
application. This is achieved via a well-defined process for data creation, usage along with appropriate
usage of tools for comprehensive test coverage.
Case Study:
Project:
Development of strategic platform which caters to institutional clients of a major investment bank. The
requirements included providing the clients a Real time view of Holding, Performance, Reference, Risk
and Transaction data with very specific visual requirements on how the data is to be shown to the end
user.
Challenges:
Multiple Data sources providing all of this data in different formats.
Multi-tiered service oriented architecture.
This data also had both compliance and organizational restrictions as this was sensitive real
client data.
The data had to be transformed from its raw form to meet the Visual requirements.
Objective:
Data integrity must be maintained at all costs. Response time of the application is expected to be below
3 seconds irrespective of the data being shown to the client.
