Once one or more plugins have been identified as promising, it’s time to test them more thoroughly.
This second step in the WPDistrib protocol aims to simulate real integration in an environment close to your current WordPress setup.
It allows you to evaluate technical compatibility, ease of configuration, and relevance in a real-world context.
At the end of this phase, an initial judgment can be made to decide whether the plugin deserves to go further.
Focus on plugins selected after initial screening
At this stage, it’s no longer about comparing dozens of plugins.
Thanks to the pre-selection phase, you should now have identified one to three plugins that deserve a deeper test. This funnel approach is essential to save time and avoid scattering your efforts.
Advanced testing therefore focuses only on the most promising plugins identified earlier.
Create a clone of the site where the plugin will be used
Advanced testing should not be done blindly, nor on an empty site.
The ideal is to duplicate an existing WordPress site or, failing that, to create a development site that faithfully reproduces the structure, theme, content, and plugins of the actual site where the plugin will be installed.
This cloning allows you to:
- Observe real-world integration,
- Replicate possible interactions with other components,
- Detect conflicts or unwanted effects that wouldn’t show up on a clean site.
This clone can be hosted locally (using LocalWP or DevKinsta), or on a temporary subdomain if working online. Many hosts offer Softaculous, which lets you clone your WordPress site in one click.
Check technical integration in your WordPress environment
Once the cloned site is ready, you can install the shortlisted plugins one by one and observe their overall behavior.
Key points to check:
- Does the plugin activate without errors (check with Query Monitor) ?
- Does it integrate cleanly into the WordPress interface (menus, blocks, widgets) ?
- Does it cause conflicts or slowdowns with existing plugins (measurable with Code Profiler) ?
- Does it add unnecessary scripts or styles to the frontend?
- Does it respect the theme’s architecture (e.g., FSE vs Customizer) ?
The goal is to determine whether the plugin behaves well in a real environment or if it requires technical or UX adjustments.
Test multisite behavior if your project requires it
In a WordPress multisite setup, this step is crucial.
You need to check:
- If the plugin can be network-activated or activated per site,
- If it works correctly across multiple subsites,
- If it keeps consistent settings across sites,
- If it creates shared tables or data without breaking multisite logic.
A good plugin should be able to adapt to a multisite environment without compromising stability or subsite customization.
Even if you’re not using multisite now, this check may be useful if you plan to scale your structure (e.g., a network of sites, shared documentation base).
Configure the plugin as if used in real-world conditions
Expanded version:
This step takes more time, as it’s not just about activating the plugin, but about truly using it within your site’s context.
Depending on the plugin, this phase may be quick (e.g., a small avatar plugin) or require several hours (e.g., newsletter tool or dynamic form builder).
Objectives:
- Explore all available options, including advanced ones.
- Test real-life use cases (adding blocks, sending emails, customizing visuals… ).
- Observe the configuration flow: is it smooth? Intuitive? Well guided?
- Evaluate built-in documentation, contextual help, or error messages.
This phase is crucial to assess how usable the plugin is in a real project, without requiring advanced technical skills.
Identify blocking issues or inconsistencies
This is often where doubts start to appear.
Even a promising plugin may reveal:
- Poorly explained options,
- A cluttered or confusing interface,
- Significant limitations in the free version,
- A long, tedious, or unreliable configuration process,
- Recurring bugs or unexpected behavior.
Rather than working around these problems, it’s important to document them clearly, identify what is blocking, and assess their real impact on the user experience.
If these issues are deal-breakers, it’s better to end the test at this stage.
Summarize the tests and form an initial reasoned opinion
After testing the shortlisted plugins, it’s time to make a decision.
There are three possible outcomes:
- One plugin stands out clearly → proceed with real production testing.
- Several plugins are equally good → continue with the best-integrated one, or keep the other “under watch”.
- None are convincing → mark the plugins as not recommended, with supporting arguments.
🌀 A realistic test to make the right decision without surprises
This advanced test phase is a critical step between theory and real-world use.
It allows you to:
- Gain confidence before introducing a new plugin to your live site,
- Objectively filter what works and what doesn’t,
- Document test results to support future decisions.
Once this phase is successfully completed, the plugin can move on to the final stage: extended testing in a live production environment.
