Background

I recently came across an article about an API test automation platform on TesterHome. After giving it a try, it got me thinking about test automation in general — and why most manual testers feel these platforms are so hard to use. Please take this as my personal take, not absolute truth.

1. What Should API Automation Really Validate?

In my opinion, before doing anything, you should clarify your motivation and goal. That alone can save you from many unnecessary detours.

Why Automate?

Industry hype: automation improves efficiency and quality.
It’s a KPI task.
You have scenarios that need frequent execution.
You want to increase confidence and reliability.

Ideal Goals

Scheduled online monitoring to catch issues earlier and reduce recovery time.
Aid regression testing — yes, just an aid. Don’t expect automation to find major bugs.
Record monitoring results to help the team understand historical system performance.

Guiding Principles for API Automation

At its core, API automation revolves around three steps. There’s nothing overly fancy. The real value still comes from the tester’s domain knowledge in creating effective test points.

We plan test points and implementation based on these three steps and the goals above:

Tool selection principles
Extracting key test points (see table below)
Handling tricky test scenarios — Most can be solved with a test framework; the rest via workflow; if still unsolved, drop it — automation is only a supporting measure

I’ll use pytest as an example here, but the ideas apply to other frameworks as well.

Tool Selection Principles

Principle	Explanation
Fit for purpose	Choose tools that match your project’s actual needs, not the hottest tech
Low learning curve	The team should be able to pick it up quickly
Easy to maintain	Scripts/cases should be readable and modifiable by anyone on the team
Good debugging experience	When a test fails, you should quickly know why
Integrates with existing stack	Plays nicely with your CI/CD, reporting, and version control

Key Test Points to Extract

Test Category	What to Validate	Example
Basic connectivity	Can we reach the API?	HTTP status code (200, 401, 404, 500, etc.)
Request/response structure	Are required fields present? Data types correct?	JSON schema validation, field presence/absence
Business logic	Does the API do what it’s supposed to?	Creating an order updates inventory, sends notification, etc.
Edge cases	How does it handle boundary values, missing params, invalid types?	Empty string, negative number, SQL injection attempt, malformed JSON
Data persistence	Is data correctly written to the database?	After POST /user, check the users table for the new record
State management	Does the API correctly handle state changes?	After DELETE /order, GET /order returns 404
Idempotency	Multiple identical requests produce the same result?	PUT /resource/1 with same payload twice → same response
Error messages	Are error responses informative and consistent?	Validation failures return 400 with clear “field X is required”
Performance baseline	Response time under normal load	95th percentile < 200ms for a typical GET request

Common Implementation Challenges and Solutions

Challenge	Typical Solution (in pytest or similar)	When to Accept It
Test data dependencies	Fixtures with scope=“session” or “module” to set up once and reuse	Use real test data if setup cost is low
Chained API calls	Pass data between tests using a shared context dict or class attributes	If the chain is very long (10+ steps), consider testing links individually
Authentication / tokens	Fixture that obtains a token and injects it into all requests via a session object	Manual token refresh in each test if it’s a one‑off
Asynchronous operations	Use time.sleep() sparingly; better: poll with a timeout + retry logic	If the async job completes within 1‑2 seconds, a simple sleep is fine
Database validation	Use a dedicated test database + rollback transactions per test	Skip DB validation if the API’s response is sufficient
External mock services	Use pytest-mock or unittest.mock to patch external calls	Call the real external service if it’s a stable sandbox
Parameterized testing	@pytest.mark.parametrize for different inputs/expected outputs	Write separate test functions if there are only 1‑2 cases
Test ordering	Design tests to be independent; use pytest‑order only as last resort	Accept order dependency for a small, stable suite

2. Real Pain Points in Automation

Current discussions focus heavily on technology. But the real pain points of automation are actually human:

(1) Growing Work vs. Limited Manpower

Limited testing resources can’t keep up with increasing demands.
Introducing automation doesn’t reduce workload — instead, you must squeeze time and resources to maintain a supporting system.

(2) Idealistic Vision vs. Practical Feasibility

Overly complex platform designs try to cover everything, leading to tedious test creation and a steep learning curve.
The desire to fit every project’s needs forces constant componentization, which kills flexibility and increases maintenance costs.

(3) Tech Pursuit vs. Actual Needs

People chase advanced, complex tech to show off skills, resulting in complicated solutions for simple problems.
Over‑abstraction makes code hard to understand and maintain (we’re not developers — no need for defensive programming).

How to Address These

Base automation on real project needs. Focus only on core functions and business flows of the current project. Don’t blindly chase coverage. Automate only critical paths, core features, and high‑risk scenarios. You don’t always need a full test platform.
The best value for API automation is scripting + a mature framework (copy‑paste is really convenient). Avoid fancy wrappers and platforms. Keep scripts readable and easy to maintain.
Don’t chase advanced tech — focus on practicality and speed. The key isn’t what technology you use for assertions; it’s whether your test case is pointing in the right direction. (Is there a real difference in test outcomes between building assertions via a Java platform vs. writing a Postman script?)

3. How to Actually Do API Automation Right

Rough Steps to Build Automation

Choose a suitable tool.
Based on the key test point extraction table above, decide what to assert.
Use CodeGeeX or GPT to help build the automation step by step.
As your tests grow in number and complexity, solve problems as they arise. You can’t anticipate everything upfront.

Recommended Python Stack (for HTTP)

If you’re using Python, here’s a typical stack (for HTTP; for other protocols, find corresponding libraries):

Component	Tool	Purpose
Test framework	pytest	Write and execute tests, support parameterization, fixtures, etc.
HTTP requests	requests	Send GET, POST, PUT, DELETE, etc.
Data driver	yaml + PyYAML	Store test data like request parameters and expected responses
Database connection	mysql-connector-python	Connect to MySQL, validate data consistency
Logging	logbook	Record execution logs for debugging
Reporting	allure-pytest	Generate detailed, visual test reports with history

4. Why Traditional Test Platforms Fail Manual Testers

The core problem is losing touch with real users. Many platforms claim “unique test writing” and “low barrier, easy to use,” but they’re often just crude web versions of JMeter or Postman, or bizarre low‑code drag‑and‑drop interfaces. They make test creation inflexible, debugging time‑consuming, and over‑componentization leads to a steep learning curve — without the transferable skills of tools like JMeter.

Common Frustrations with Platforms

Cumbersome workflow: Create project → create module → create case → associate project → associate module.
Tedious case editing: Multiple input boxes for request parameters, pre/post scripts, expected values. When an interface changes, you manually update each case one by one. Poor readability, high maintenance.
Debugging pain: Unclear, slow debugging info. When something fails, you can’t tell if it’s the platform’s fault or the API’s.

Design Flaws in Test Platforms

Flaw	What It Looks Like	Why It’s a Problem
“No code” obsession	Drag‑and‑drop, visual workflow builders	Actually slower than writing a few lines of code. Hard to version control.
Over‑generalization	Endless configuration options to handle “every possible scenario”	Analysis paralysis. Most options are never used.
Component explosion	Pre‑request scripts, post‑request scripts, conditionals, loops, variables, etc. as separate visual blocks	Learning the platform becomes harder than learning the underlying framework.
Vendor lock‑in mindset	Proprietary ways of defining tests that don’t map to standard tools	Skills don’t transfer. You’re stuck if the platform dies or gets abandoned.
Poor debugging UX	“Test failed” with no stack trace, no request/response diff, no logs	Wastes hours figuring out whether the bug is in your test or the system under test.
Performance theater	Built on a fancy React/Vue frontend + microservices backend for a simple task	Slow to load, slow to run. The original pytest finishes in 2 seconds; the platform takes 30 seconds just to start.

Mindset Gap

We’re not in the era where manual testers are code‑illiterate. Most job interviews for functional testing now require basic scripting skills. And with GPT, the “no‑code” concern is even less relevant.
Testers want to improve their coding skills through scripting. Even if it’s tedious, there’s a sense of growth and achievement.

5. Psychological Traps in Writing Automation

(1) Feeling Guilty for Not Using Design Patterns

Newcomers often feel that not using design patterns makes their automation less professional. Yes, design patterns can improve maintainability and scalability, but not every project needs them. For simple interface tests, introducing patterns only adds complexity and maintenance overhead. Design patterns should evolve as needed — don’t do them for their own sake. Focus on writing simple, readable, maintainable scripts.

Even a straightforward structure like this is perfectly fine if it meets your goals:

project_root/
|-- api_tests/
|   |-- project1/
|   |   |-- __init__.py
|   |   |-- test_api_project1.py
|   |   |-- utils/
|   |       |-- __init__.py
|   |       |-- api_client_project1.py
|   |-- project2/
|       |-- __init__.py
|       |-- test_api_project2.py
|       |-- utils/
|           |-- __init__.py
|           |-- api_client_project2.py
|-- conftest.py
|-- pytest.ini
|-- requirements.txt

(2) Obsessing Over Tools Instead of Test Goals

Whether it’s Java TestNG, Python pytest, JMeter, Postman, or a platform built on top of them — all do the same thing: send requests and assert responses. No matter how complex the implementation, the test goal remains identical. The real challenge is always test case maintenance and management, even on platforms. The quality of test case design and execution directly impacts effectiveness. Poorly designed cases miss important issues.

(3) Believing Everything Can Be Automated

Automation is an abstraction of business logic. Compared to manual testing, it’s indeed more efficient, but only under one essential condition: a stable project.

(4) Trying to Do It All at Once

Don’t try to cover all interfaces and scenarios from day one. That adds unnecessary pressure and maintenance cost. Start incrementally: begin with a few core interfaces and key scenarios, then expand gradually.

6. Conclusion: What Actually Works

After all the criticism above, let me summarize what actually works for API automation:

What Doesn’t Work	What Actually Works
Bloated “universal” test platforms	Scripting + a mature framework (like pytest)
Over‑componentization and endless config options	Simple, readable, copy‑paste friendly scripts
No‑code drag‑and‑drop that’s slower than coding	Writing actual code with GPT/CodeGeeX assistance
Trying to automate everything from day one	Starting small with core paths, then expanding
Chasing advanced tech to show off skills	Focusing on practicality, speed, and real test value
Proprietary platform logic that doesn’t transfer	Standard tools with transferable skills (pytest, requests, etc.)

The bottom line: The key to good API automation isn’t the tool or platform you use. It’s whether your test cases point in the right direction, based on solid business understanding. Keep it simple. Keep it maintainable. And remember — automation is only a supporting measure, not a silver bullet.
