What is Installation Testing

Installation testing is a critical part of the software development and deployment process. It refers to testing conducted to ensure a particular software or application is correctly downloaded, properly installed, and functions as expected on a machine.

Performing thorough installation testing helps companies avoid various risks that come with failed or flawed software deployments.

Goals of Installation Testing

Before software or an application is released to end-users, companies conduct rigorous installation tests that evaluate a wide variety of factors.

These tests confirm the software works with target operating systems, runs with appropriate security settings, performs well across supported browsers, and integrates smoothly with any systems already on a machine.

Comprehensive installation testing ultimately verifies that users can simply download an application. This is whether to a PC or mobile device, follow straightforward prompts, and have the software fully operational in a short time. 

Importance for Cloud-Based Software

As more companies deliver software and applications via the cloud, properly testing installations is as important as checking functionality.

While developers conduct unit tests that isolate modules of code, installation testing focuses on replicating and validating the entire end-user process.

That requires understanding specifications, modeling real usage, meticulously testing across supported platforms, documenting issues, addressing identified problems, and iterating until deployment meets standards.

Importance of getting Installation Testing Right

Avoiding Risks and Issues

Properly executing installation testing is critical for avoiding numerous risks and issues once software is deployed to customers.

Without rigorous testing, problems encountered by users can include the following; programs failing to load correctly, features not functioning as expected, software conflicts slowing down machines, and errors that compromise security.

In some cases, flaws in installation testing can even render applications unusable for customers. This leads to frustrated users who may lose confidence in the software and the brand behind it.

Additionally, problems that escape testing create unnecessary support burdens for provider companies.

For software providers in regulated industries like healthcare, financial services, and accounting, installation testing takes on added legal importance.

Proper functionality testing ensures compliance with government rules related to security, data integrity, auditability, and more.

Failed compliance poses financial penalties and other legal liabilities.

Reputational Damage

Insufficient installation testing procedures that result in software issues making it to customers can significantly hurt provider reputations.

Companies that release programs with installation problems that impact reliability or data security suffer lasting reputational damage.

This loss of credibility and trust can be difficult to recover from.

Software Installation Testing

Software installation testing involves the following;

Testing OS Integrations

A key aspect of software installation testing is evaluation. This involves checking how new applications interface and integrate with underlying operating systems once downloaded.

Rigorously testing software on supported Windows, Mac OS, Linux, and mobile platforms verifies correct functioning across devices users already own.

Thorough testing evaluates potential issues like software installation conflicts, crashes on certain OS versions, dragging performance due to OS communication failures, or platform-dependent bugs. Identifying and addressing integration issues during installation testing is crucial for smooth functioning post-deployment.

Confirming Driver Operations

Many software packages require specific drivers to enable communication between programs and device hardware components.

Installation testing protocols include validating that necessary driver installations complete correctly across supported platforms.

Proper driver functioning is essential for some software capabilities. For example, a video editing application requires drivers to harness graphics card GPUs for rendering effects and playback.

Installation testing checks drivers work post-installation.

Verifying Configuration Settings

Some enterprise software products require extensive configurations with security settings, user permissions, database connections, and more that enable core capabilities.

Rigorous installation testing is necessary to confirm configured settings are properly implemented as intended on users’ systems.

Any configuration discrepancies that allow flaws in security policies, accessibility rules, or data connections can severely impact software functionality. Also, it can affect areas of compliance.

Software installation testing verifies that configurations are accurately set up.

Application Installation Testing

Application installation testing focuses on verifying that a deployed software correctly implements critical architecture. It does this to ensure that it delivers intended functionality and data access across an enterprise environment.

Testing evaluates how installation procedures establish application frameworks, security models, integrations, and user settings that enable performance to specifications.

Validating Application Architecture

Testing the underlying application architecture ensures system components like the user interface, data tiers, processing engines, and APIs are configured correctly upon installation.

Flawed application architectures can prohibit software capabilities from working properly post-deployment.

Checking Security Models

Stringent testing is necessary to validate installation processes appropriately implement the following; important security controls, authentication protocols, access limitations, and necessary encryption.  

All these are very important for an application to maintain data protection policies. Any installation shortcomings in security foundations open unacceptable risks.

User Acceptance Testing

Once installation testing confirms foundational application architecture and security controls are established correctly, user acceptance testing simulates real-world access scenarios across employee roles.

Testing verifies users can securely use the application’s full range of features and data in compliance with business policies.

Installation Testing Best Practices

It is very important for installation testing to be up to standard. Therefore, to ensure that installation testing efforts are rigorous, structured, and repeatable across software development initiatives, leading industry protocols dictate several key best practices:

Understanding Requirements

There is a foundation for devising a thorough installation test plan. This is completely understanding the functional and technical specifications of the software application under development.

Relevant questions to ask here include; What core user tasks is it intended to accomplish? What platforms and OS does it support? What drivers, browsers, or ancillary software does it require? The clearer the requirements, the better the tests.

Comprehensive Test Cases

With requirements setting capabilities boundaries, comprehensive test cases specifically model high priority tasks, system configurations, and access workflows.

Test cases align to specifications but take an expansive view of potential use scenarios.

Testing installations against rigorous test cases identifies a majority of deployment problems.

Simulating Real-World Conditions

The environments used in installation testing should mirror the actual usage conditions of end users as closely as possible.

Using real devices, OS versions, ancillary software stacks, and network infrastructures allows tests to uncover installation problems that may come up in the field.

Documenting Execution

Documentation is critical for analyzing test results, addressing identified errors, and preventing issues in future software builds.

Installation testing requires thoroughly documenting test case specifics, test system environments, exact test steps, observational logs, screenshots or videos, and test reporting.

Documentation supports continual optimization.

Planning Effective Installation Tests

Execution of installation testing requires careful advance planning to ensure methodical evaluation of all parameters that can influence deployment outcomes. Planning considerations when developing installation test protocols include:

Following Established Protocols

Quality assurance teams create installation test plans using established software testing methodologies that prioritize critical functional and technical elements.
