qamigrate 0.2.0

AI-powered Selenium to Playwright migration tool

QAMigrate

AI-powered test framework migration

A QATonic Innovations product.

---

QAMigrate converts test suites between frameworks automatically. It parses your code with Tree-sitter, generates equivalent code with Claude, and produces a full migration report with per-file diffs, confidence scores, and estimated time savings.

Today: Selenium Java -> Playwright Java Next: Cypress -> Playwright, TestNG -> JUnit 5, RestAssured -> Karate, and more.

Why QAMigrate

You don't just get generated code. You get evidence:

• Per-file diffs -- every pattern we touched, why, and side-by-side before/after
• Confidence score -- how sure we are about each file, 0 to 100
• Batch report -- HTML, JSON, and Markdown; share with your team
• Time-saved estimate -- how many hours of manual work you avoided
• Dry-run mode -- preview what would change without calling the LLM

What it does

Give it a Selenium file:

// Selenium
@FindBy(id = "username")
private WebElement usernameInput;

public void login(String user, String pass) {
    usernameInput.clear();
    usernameInput.sendKeys(user);
    passwordInput.sendKeys(pass);
    wait.until(ExpectedConditions.elementToBeClickable(loginButton));
    loginButton.click();
}

Get Playwright back:

// Playwright (generated by QAMigrate)
private final Locator usernameInput;

public LoginPage(Page page) {
    this.usernameInput = page.locator("#username");
}

public void login(String user, String pass) {
    usernameInput.fill(user);
    passwordInput.fill(pass);
    loginButton.click(); // Playwright auto-waits
}

Supported patterns (Selenium -> Playwright Java)

• @FindBy annotations (id, css, xpath, className, name, linkText)
• PageFactory.initElements removal
• WebDriverWait / ExpectedConditions removal (Playwright auto-waits)
• sendKeys -> fill, clear removal, click direct conversion
• Actions (hover, drag) -> Playwright equivalents
• Select dropdowns -> selectOption
• JavascriptExecutor -> page.evaluate()
• Alert / iframe handling
• File uploads -> setInputFiles
• TestNG -> JUnit 5 lifecycle (@BeforeMethod -> @BeforeEach, etc.)
• @DataProvider -> @MethodSource
• Assert.assertEquals / assertTrue -> Playwright assertions
• ChromeDriver setup -> Playwright.create() + browser.newContext()
• Base class inheritance preservation

Quick start

Prerequisites

• Python 3.11+
• Java 17+ (for compilation validation; optional — see compiler.skip)
• Anthropic API key

Install

pip install qamigrate

Configure

echo "ANTHROPIC_API_KEY=sk-ant-your-key" > .env

Migrate

# Dry-run: see what would happen without calling the LLM
qamigrate migrate --all --project ./my-selenium-project --dry-run

# Migrate a single file
qamigrate migrate src/test/java/LoginPage.java --project ./my-selenium-project

# Migrate everything with a full migration report
qamigrate migrate --all --project ./my-selenium-project --report ./qamigrate-report

Output goes to playwright/ subdirectories next to each original file. If you use --report <dir>, you get report.html, report.json, and report.md.

Example report summary

QAMigrate - Migrating 7 file(s)

-> [1/7] BaseTest.java
   OK src/.../playwright/BaseTest.java (14.1s, 75% confidence)
-> [2/7] LoginPage.java
   OK src/.../playwright/LoginPage.java (17.2s, 75% confidence)
...

Files             7 / 7
Patterns handled  149
Avg confidence    75%
Time              105.3s
Est. hours saved  ~37.2

Report written:
  HTML:     ./qamigrate-report/report.html
  JSON:     ./qamigrate-report/report.json
  Markdown: ./qamigrate-report/report.md

CLI commands

Command	Description
qamigrate init	Initialize QAMigrate in a project
qamigrate scan	Analyze codebase, detect patterns, show complexity
qamigrate migrate	Convert files to the target framework

Common flags for migrate:

• <file> — migrate a single file
• --all, -a — migrate all Java files under src/test or src/
• --dry-run — analyze only, no LLM calls, no writes
• --report <dir> — write HTML + JSON + Markdown report
• --project, -p <path> — project root (default: current dir)

How it works

Scanner (Tree-sitter)     Deterministic AST parsing, pattern detection
       |
Coder (Claude API)        Generates Playwright Java via structured output
       |
Compiler (javac)          Validates generated code compiles
       |
Fixer (rules + Claude)    Fixes compilation errors, retries up to 3x
       |
Report                    Records everything that happened

Plain Python — no LangChain, no graph framework, no agents-of-agents. Each step is a clean module you can read in 5 minutes.

Configuration

Optional qamigrate.yaml in your project root:

pipeline:
  max_retries: 3

coder:
  model: "claude-sonnet-4-20250514"
  max_tokens: 8192

compiler:
  build_tool: "maven"    # or "gradle"
  java_version: "17"
  skip: false            # set true when Playwright JARs aren't on classpath

scanner:
  exclude_patterns:
    - "**/target/**"
    - "**/build/**"
    - "**/playwright/**"

You can also use environment variables with the QAMIGRATE_ prefix:

export QAMIGRATE_COMPILER__SKIP=true       # skip compilation check
export QAMIGRATE_PIPELINE__MAX_RETRIES=5   # more retries

Python API

from qamigrate.agents.pipeline import run_migration
from qamigrate.core.config import QAMigrateConfig
from qamigrate.core.report import MigrationReport

config = QAMigrateConfig()
report = MigrationReport()

result = run_migration(
    file_path=Path("src/test/java/LoginPage.java"),
    project_path=Path("."),
    config=config,
)

if result.record:
    report.add(result.record)

report.finish()
report.write_html(Path("./report.html"))

Development
