A Complete Guide To Crowdtesting

Imagine an e-commerce app developed in the USA that functions smoothly during testing but crashes when launched in Asia, due to issues with local currency and credit card support. It’s impossible to replicate the diversity of projected 6.4 billion users, user flows, and corner cases worldwide with in-house testing.

Before launching your product globally, you must consider how you will address critical QA aspects such as:

• Localization Testing, including validation of local languages and locations.
• Device Testing to ensure coverage on devices that dominate specific regional markets.
• Accessibility Testing to meet global accessibility standards.
• Payment Testing to verify transactions with local banks, debit cards, and credit cards.

Failing to address these areas introduces risks that can delay your product goals, including costly launch delays, user trust, and reputational damage. At Global App Testing, we’ve observed that even experienced in-house QA teams can face challenges in achieving the same scale and coverage needed to identify every real-world issue before release.

This is where crowdtesting teams step in as a right-hand to in-house QA teams, covering the areas that impact global users.

In this blog, we’ll unpack what crowdtesting is, its available types, its benefits and challenges, and how it works in practice. 

What is Crowdtesting?

Crowdtesting brings experienced professionals to evaluate apps on real devices across various locations, replicating realistic user conditions. In-house testing teams cannot replicate the mix of local networks, OS versions, and usage patterns that crowdtesters provide. 

Crowdtesting Approach

Below are the top five attributes that make crowdtesting a powerful addition to QA strategies:

1. Scalability: Crowdtesting vendors, global testers can be added and reduced according to customer demand. 
2. Real-world validation: Through crowdtesting, testers from around the globe ensure product performance across diverse devices, networks, and environments. 
3. Global reach: Crowdtesters test the product in various locations, time zones, and languages to ensure it works for international users.
4. Integration with existing tools: Crowdtesting teams complement your testing strategy, adapting your tools (e.g., Jira, qtest) to keep focus on execution rather than changing tools.
5. Cost-effectiveness: QA teams scale on demand with crowdtesting vendors, and maintain efficient budgets while keeping resources focused on product development.

Understanding the basics sets the stage to explore the core types of crowdtesting and how each addresses gaps that in-house QA alone cannot cover.

The Main Types of Crowdtesting

Crowdtesting teams at GAT cover a wide range of testing types and areas, including exploratory testing, payment testing, and localization testing. Each type strengthens QA coverage by addressing different real-world challenges.

Let’s look at these types and what they deliver in detail:

Five key types of crowdtesting

1. Distributed testing 

Distributed testing involves testers working across multiple time zones and regions to validate products on diverse devices and environments. This global distribution of tests improves overall test execution time.

2. Exploratory testing

Exploratory testing is a free-style scenario-based approach in which the testers go through the application to uncover edge cases. In our experience with global products, we have observed that in-house teams, who use the product daily, often overlook bugs that may only be identified by first-time users. This is achieved through exploratory testing.

3. Localization testing

Localization testing involves a diverse group of local testers from target markets to ensure language, location, and payment flows are accurate. Global App Testing helped Carry1st and improved checkout completion by 12%. This testing ensures a product is truly global-ready.

Benefits and Challenges of Crowdtesting

Crowdtesting offers powerful advantages to QA teams, but it also comes with challenges and misconceptions, which often cause QA leaders to hesitate in fully adopting it. Understanding both sides ensures organizations make informed decisions.

Benefits, Challenges, and Misconceptions of Crowdtesting

Let’s carefully analyze the benefits of crowdtesting.

Benefits of Crowdtesting

Modern QA teams face mounting pressure to deliver quality at speed. Crowdtesting helps bridge this gap by offering tangible advantages:

• Faster QA cycles: With distributed testers worldwide, validation continues around the clock, accelerating release readiness. Take the example of our Fintech Client, which reduced release cycles by 30% and achieved 24/7 Tester Availability.
• Increased coverage: In-house teams can’t test on multiple devices, OS, and network conditions available through crowdtesters. For instance, Eventbrite benefited from GAT to test for global audiences, locations, and usability issues.
• Regulatory and accessibility compliance: Testers verify accessibility standards to determine whether products meet industry standards in various contexts, particularly in the healthcare and banking sectors. One of our healthcare clients utilizes crowdtesting to ensure compliance with HIPAA and accessibility standards for patients with disabilities.
• Scalable without inflating QA headcount: Crowdtesting ensures that the QA team is not shorthanded when launching globally by scaling the team on demand. For example, A retail app scaled QA across multiple regions during the peak holiday season without increasing internal staff, using GAT’s flexible tester pool.

Despite its many strengths, crowdtesting is often surrounded by misconceptions and a few practical challenges that teams should be aware of.

Common Challenges and Misconceptions of Crowdtesting

Many QA teams recognize the power of crowdtesting, especially its ability to deliver speed and global coverage. Still, QA leaders hesitate to adopt crowdtesting due to misconceptions or perceived challenges. 

Let’s look at these challenges and misconceptions in detail: 

Challenges

• Test data and credential management:  Securely managing sensitive data and credentials across distributed testers can be difficult, as you would require strict access controls during testing and processes backed by proprietary NDAs.
• Cost concerns: Managing budgets with quality outcomes can be difficult. Without flexible pricing models from vendors, it might be expensive to scale testing efforts internally.
• Coordinating distributed testers: The coordination of testers working from many regions and time zones, scheduling, and managing consistency in execution can be challenging.
• Consistency in exploratory testing: Exploratory crowdtests can rely on the testers’ perspective. Different QAs may approach the same flow in different ways, resulting in inconsistency in results.

Misconceptions 

Many concerns about crowdtesting stem from outdated assumptions. Let’s analyze these misconceptions against the realities of today’s crowdtesting practices and uncover why they no longer hold back modern QA teams.

By overcoming these challenges, crowdtesting becomes a scalable, strategic layer of modern QA strategies, transforming it from a tactical add-on into a core accelerator for every release.

How Does Crowdtesting Work?

In practice, specialized vendors fully manage crowdtesting teams and activities. They help with test case identification and execution to find regional gaps that in-house teams might miss. Dedicated crowdtesting coordinators ensure actionable and structured feedback cycles. This saves the time of in-house teams as  QA managers don’t need to go back and forth with the crowdtesting team.

While the core activities of crowdtesting show their value, the real strength lies in how these steps are structured into a repeatable, streamlined process.

The Crowdtesting Process (Step-by-Step)

Many QA teams struggle to integrate crowdtesting into their release cycles efficiently. Crowdtesting is not only about outsourcing tests. It’s a process of structured collaboration that includes definving test objectives, adding test estimates, reviewing results, and adding crowdtesting in each release.

1. Define Test Objectives

The initial step of crowdtesting is defining objectives. This is done in collaboration with the crowdtesting partner, QA managers, and product owners. This step answers the question: What would you like to validate: functionality, performance, localization, or accessibility? 

2. Select the Vendor

One of the biggest challenges is choosing the right crowdtesting partner. The right vendor balances device coverage, tester quality, and secure, actionable reporting, helping QA teams validate apps efficiently without workflow disruption. 

3. Choose Test Scenarios

Test scenarios are divided into two types: Pre-build and Custom scenarios. 

• Pre-built scenarios accelerate testing for standard workflows, such as login, checkout, or navigation.
• Custom scenarios target specific features, edge cases, or user behaviours.

At GAT, QA teams provide both options, featuring a global library of validated scenarios that significantly reduces test design time. This step ensures coverage aligns with product goals.

4. Execute Tests

The crowdtesting team executes tests across devices, operating systems, browsers, and network conditions. Testers identify bugs and performance issues and submit reports to crowdtest coordinators.

5. Roles and Collaboration

Successful crowdtesting is never an individual effort. It requires clear collaboration between internal teams and external testers to align objectives, context, and execution.

• QA managers oversee objectives and priorities. 
• Product owners provide business context. 
• Crowdtest coordinators manage execution and Integration with internal QA and automated testing to ensure that manual and automated insights complement each other.

6. Analyze Results

The report is analyzed collaboratively to identify bugs, usability gaps, and performance bottlenecks. Loops of feedback during the development cycle reduce post-launch issues by addressing bugs early.

7. Continuous Integration

Crowdtesting is not a one-off task but an action item in every product release. This ensures that both current and new features are thoroughly tested.

With these stages in place, crowdtesting transcends one-off validation and becomes a trusted supplement to the QA process. But how does it fare against in-house testing methodologies?

Crowdtesting vs. In-House QA

When companies are expanding globally, their QA teams have to determine if they are going to scale their in-house QA teams or work with crowdtesting services. Both options are worthwhile. In-house QA understands its product in-depth, whereas crowdtesting provides sophisticated tools and expertise.

To simplify the decision, here's a side-by-side comparison of where in-house QA is particularly good and where crowdtesting brings specific value to augment overall QA coverage.

This comparison makes it clear that crowdtesting and in-house QA are not competing approaches but complementary ones.

In-house teams bring deep product knowledge, while crowdtesting expands coverage to global devices, networks, and real-world conditions. Together, they create a stronger QA strategy that strikes a balance between speed, scale, and quality. 

Best Practices for Modern Crowdtesting

Crowdtesting reaches its maximum value if it’s embedded into regular QA workflows rather than serving as a supplement to standard QA procedures. Below are best practices that can help crowdtesting provide faster, deeper coverage, and meaningful insights:

1. Add crowdtests with sprint cycles: Incorporating crowdtesting into your sprint cycle ensures quality in your product with each iteration.
2. Blend exploratory and scripted tests: Exploratory tests identify edge cases while scripted tests validate end-to-end workflows. A combination of both approaches ensures thorough coverage of the user flows.  
3. Focus on core business flows: Select the flows that are most critical to your business to prevent bugs in production. For example, for an ecommerce app, checkout, payment flows, and integrations often have the highest business impact. 
4. Maintain continuous feedback loops: Keep constant feedback loops in place by utilizing real-time reporting and integrating tools like Jira to escalate issues earlier. 
5. Select a partner that ensures scalability: Select a partner that can scale up as your business needs evolve.

By following these practices, organizations achieve faster releases, reduced QA overhead, and greater confidence in global user experiences.
