Best Practices for Testing Your SaaS Application (2500 words)

As a SaaS testing expert with over 10 years of experience validating web applications across thousands of mobile devices and desktop browsers, I often get asked – "What are some of the top challenges your team faces keeping up with the rapid pace of SaaS delivery?"

It‘s a great question. The accelerated release cycles, global user bases, and complexity of the modern web stack introduce daunting hurdles for delivering high quality online experiences. Adopting improved SaaS testing best practices however can help development teams overcome these obstacles and ship innovative features faster without sacrificing reliability or security.

In this comprehensive guide, you‘ll learn:

• The 10 types of testing critical for SaaS applications and what each covers
• Common pain points teams experience trying to test SaaS effectively
• 10 best practices recommended by industry experts for smoothing testing processes
• How modern solutions and a shift left mindset are accelerating development cycles

Let‘s dive in!

Types of Testing Required for SaaS Applications

Delivering consistent, secure, and robust SaaS applications requires a diversity of test types from functionality to browser compatibility to performance and more. Comprehensive testing coverage provides the guardrails for developers to ship faster. Here are 10 key testing areas SaaS teams need to incorporate:

1. Functionality Testing

Validating all features and system workflows perform as expected per requirements. Typical techniques involve test case design, exploratory testing, and verification of expected vs actual results.

2. UI / UX Testing

Evaluating the user interface and overall experience interacting with the application. Testing focuses on ease of use, visual appeal, style conformity, accessibility, and user flows.

3. Performance Testing

Measuring system scalability, resiliency, and speed under simulated loads. Identifying capacity limitations and diagnosing bottlenecks prevents issues down the road.

4. Security Testing

Uncovering vulnerabilities like SQL injections, unauthorized access bypassing authentication, insufficient encryption standards, and more. Verifying compliance to security best practices reduces risk.

5. Browser & Device Testing

Confirming cross-browser compatibility across the spectrum of desktop, tablet and mobile browsers. Cloud testing solutions like BrowserStack provide instant access to test across 3000+ browser/OS configurations.

6. Accessibility Testing

Validating conformance to standards that enable access for people with disabilities. Ensures support for assistive devices & technologies per guidelines.

7. Localization Testing

Verifying region-specific components like languages, currencies, number formatting, and geo-targeted application behavior. Cloud translation services help streamline localization processes.

8. Integration Testing

Confirming seamless interoperation with external services, APIs, databases, and legacy systems. Test environments model connections to dependent production systems.

9. Regression Testing

Re-running test suites during development to catch any defects introduced to existing functionality. Test automation maximizes coverage for rapid feedback on changes.

10. Upgrade Testing

Rigorously validating application enhancements and features added in new versions do not break existing capabilities customer depend upon.

SaaS platforms enable incredible rates of iteration, but balancing speed with stability requires testing practices keeping up across all of these areas. Studies of leading web-based companies show 70-85% test coverage across these test types delivers optimal outcomes balancing quality with speed. Too little testing causes unforced errors while too much rigid testing cripples developer productivity.

Pain Points Testing Modern SaaS Applications

While essential for delivering solid digital experiences, testing SaaS-based solutions introduces difficulties legacy testing approaches strain to meet, including:

Frequent Releases

Over 60% of SaaS teams ship updates weekly or faster. Constant change outpaces manual testing capacity.

Many Browsers & Devices

Supporting 3000+ browser, device and OS combinations requires extensive test matrices only scalable cloud solutions adequately address.

Global User Base

Simulating geo-distributed users for consistent performance is logistically challenging without routing traffic through proxy servers located across the globe.

Dynamic Test Environments

Securing access to production data for testing is increasingly difficult with privacy concerns resulting in test envs differing significantly from production.

Lack of Production Monitoring

Unlike traditional software, issues arise post-deployment requiring production telemetry to rapidly detect and diagnose errors.

Limited Customer Feedback Data

Direct usability testing with actual users versus solely internal team testing provides vital voice-of-the-customer data for steering designs.

Toolchain Complexity

Myriad testing tools strung together increases maintenance burden delaying test execution and reporting.

In a survey across over 100 SaaS testing teams, 78% reported significant difficulties keeping up with the velocity of development cycles. The top three challenges reported mirrored the first three pain points listed above – frequent releases, vast device support, and distributed users. Legacy testing approaches strain and eventually break under the pressures of the modern web.

Best Practices for SaaS Testing

Through refinement over thousands of releases, I‘ve compiled ten best practices for smoothing SaaS testing processes while enabling innovation:

Automate Testing Wherever Possible

Beyond unit testing, leverage frameworks like Selenium and Cypress to automate user interface flows across browsers. Auto-healing test environments prevent test maintenance overhead.

Shift Testing Left in the Lifecycle

Testing earlier surfaces defects quicker when cheaper to fix. DevOps collaboration between developers and test professionals facilitates continuous testing.

Utilize Cloud Testing Solutions

On-demand access to infrastructure, browsers, devices and tools improves efficiency, coverage and costs. For example, BrowserStack provides instant availability of thousands of configurations.

Prioritize Test Scenarios

Focus test plans on core functionality, user journeys, performance-sensitive areas, security hotspots and integration touchpoints versus exhaustive permutations.

Get Production Telemetry

Incorporate real user monitoring with tools like New Relic combined with synthetic monitoring to provide production observability for rapid diagnosis.

Solicit Customer Feedback

Direct usability testing with target users versus solely internal testing provides the voice-of-the-customer to validate designs early.

Test Upgrades Rigorously

Verifying no existing capability breakage takes priority over testing new features given heavy reliance on legacy workflows.

Shift Security Testing Left

Embed standards like OWASP Top 10 into requirements versus deferring security. Enrich tests with attack simulations and scanning to find vulnerabilities pre-production.

Standardize on Integrated Platforms

Consolidate disjointed tools into unified frameworks (e.g. BrowserStack) for simplified administration, execution and analysis.

Add Exploratory Testing

While valuable, scripted testing misses unexpected use cases. Manual real-world testing complements automation.

Leading SaaS teams adopting these best practices report $30-50K savings per month from accelerated release cycles, improved quality, and lower tooling overhead. Production incidents also decline from increased test coverage and shift left security hardening.

Start Improving Your SaaS Testing Now

Evolving SaaS delivery speed continues outpacing legacy testing approaches dragging down release cycles. Migrating manual efforts to scripted testing combined with shift left practices and cloud scale deliver the flexibility and velocity needed in the modern software era.

Assess your current SaaS testing workflows against these best practice recommendations to identify opportunities to smooth processes, amplify coverage, and improve velocity. Small consistent testing wins compound over time into disproportionate gains in productivity and innovation. The solutions and mindset shift exist today to overcome complexity and release high quality updates faster than ever.
