A powerful interactive debugger for Robot Framework with real-time test control, variable inspection, and keyword retry capabilities.

![rfdb Demo](https://github.com/suri-53/rfdb/blob/main/Screenshots/rfdbUI.png)

## 🚀 Features

- **⏸️ Pause & Continue**: Stop test execution at any failure and resume when ready
- **🔄 Retry Keywords**: Retry failed keywords with modified arguments
- **🔍 Variable Inspector**: View all variables in real-time (test/suite/global scope)
- **⚡ Run Custom Keywords**: Execute any keyword during test pause with search functionality
- **📊 Call Stack Viewer**: Navigate execution hierarchy for complex test debugging
- **🎨 Enhanced Logs**: Color-coded failure logs with structured output
- **🔎 Keyword Search**: Filter and find keywords quickly in large libraries
- **💾 Memory Efficient**: Auto-trimming logs, lazy library loading

## � How It Works

`rfdb` uses Robot Framework's Listener API v3 to monitor test execution in real-time:

1. **Listens to Events**: Hooks into test/keyword start/end events
2. **Detects Failures**: When a keyword fails, execution pauses
3. **Opens GUI**: Interactive debugger window appears automatically
4. **Blocks Execution**: Test waits while you inspect variables, logs, and call stack
5. **User Actions**: Continue, retry with modified args, or run custom keywords
6. **Resumes Tests**: Execution continues based on your action

**Non-Intrusive**: No need to modify test code - just add `--listener` flag!

## �📦 Installation

```bash
pip install rfdb
```

**Requirements:**
- Python 3.10+
- Robot Framework 7.1.1+
- tkinter (usually included with Python)

## 🎯 Quick Start

### Method 1: As a Listener (Recommended)

Run your tests with rfdb as a listener:

```bash
robot --listener rfdb your_test.robot
```

Or with multiple listeners:

```bash
robot --listener rfdb --listener OtherListener your_test.robot
```

### 2. Debug Interactively

The debugger GUI opens automatically when a test fails:
- Click **Continue** to proceed
- Use **Retry Failed Keyword** tab to retry with different arguments
- Check **Variable Inspector** to see current state
- Run **Custom Keywords** to inspect or fix issues

## 📖 Usage Guide

### Execution Control

**Pause on Failure**: Automatically pauses when any keyword fails
**Continue Button**: Resume test execution
**Emergency Exit (Ctrl+Q)**: Force-close debugger immediately

### Retry Failed Keyword Tab

1. Failed keyword appears in the list automatically
2. Modify arguments if needed
3. Click "Retry" to re-execute
4. Or click "Skip" to mark as passed and continue

```robot
# Example: Retry with corrected element locator
Click Element    id=wrong_button    # Fails
# In debugger: Change to id=correct_button and retry
```

### Run Custom Keyword Tab

Execute any Robot Framework keyword during pause:

1. **Search keywords**: Type to filter (e.g., "click", "selenium")
2. **Select keyword**: Click from filtered list
3. **Enter arguments**: Add keyword arguments (comma-separated)
4. **Execute**: Run the keyword immediately

**Supported Libraries:**
- BuiltIn
- SeleniumLibrary
- RequestsLibrary
- DatabaseLibrary
- Any custom libraries in your test

### Variable Inspector Tab

View all Robot Framework variables in real-time:

- **Test Variables**: Current test scope (`${var}`)
- **Suite Variables**: Suite-level variables
- **Global Variables**: Global scope
- **Built-in**: `${TEST_NAME}`, `${SUITE_NAME}`, etc.

Auto-refreshes every second during active execution.

### Call Stack Viewer

Click **[STACK] View** to see execution hierarchy:

```
Test: My Test Case
  └─ Keyword: Login To Application
      └─ Keyword: Input Text
          └─ Keyword: Wait Until Element Is Visible
```

## ⚙️ Configuration

Create `rfdb_config.py` in your project (optional):

```python
# Customize log limits
MAX_LOG_LINES = 2000              # Default: 1000
MAX_FAILURE_LOG_LINES = 1000      # Default: 500

# Variable refresh rate (milliseconds)
VARIABLE_REFRESH_DELAY_MS = 500   # Default: 1000
```

## 🎨 Features in Detail

### Enhanced Failure Logs

Color-coded for easy identification:
- `[FAIL]` - Failed tests (red)
- `[PASS]` - Passed tests (green)
- `[WARN]` - Warnings (yellow)
- `[KEYWORD]` - Keyword names (gold)
- `[ARGS]` - Arguments (mint green)

### Keyword Search

Real-time filtering in "Run Custom Keyword" tab:
- Type to filter keywords instantly
- Case-insensitive search
- Shows library name for each keyword
- Library status indicator

### Memory Management

- Auto-trims logs to prevent memory bloat
- Lazy-loads library keywords only when needed
- Duplicate library prevention
- Efficient variable refresh

## 🔧 Troubleshooting

**Debugger doesn't pause on failures**
- Ensure `Library    rfdb.RobotFrameworkDebugger` is in your test Settings
- Check Robot Framework version (7.1.1+ required)

**Keywords not showing in custom keyword list**
- Libraries load lazily - they appear after first import
- Click "Refresh" button to reload
- Check library is imported in your test

**Variables not updating**
- Variables only refresh during active test execution
- Switch to Variable Inspector tab to trigger refresh
- Check test hasn't already completed

**GUI not responding**
- Press Ctrl+Q for emergency exit
- Keywords have 30-second timeout protection

## 🏗️ Architecture

- **Listener API**: Uses Robot Framework v3 Listener API
- **Event-Driven**: Thread-safe GUI updates
- **Non-Blocking**: Test execution and GUI run independently
- **Memory Safe**: Bounded logs, lazy loading

## � Pro Tips

**Best Practice**: Use `--listener` flag instead of importing as library:
- ✅ No need to modify test files
- ✅ Works across all test suites
- ✅ Easy to enable/disable debugging
- ✅ Clean separation of concerns

**For CI/CD**: Simply remove `--listener rfdb` flag in automated runs

## �📝 Examples

### Example 1: Retry with Modified Arguments

```robot
*** Test Cases ***
Login Test
    Login To System    wrong_user    wrong_pass
    # Debugger pauses - correct credentials in retry tab
    # Click Retry with: correct_user, correct_pass
```

### Example 2: Custom Keyword Debugging

```robot
*** Test Cases ***
Element Test
    Click Element    id=button
    # Fails - element not found
    # In Custom Keyword tab:
    #   1. Search "wait"
    #   2. Select "Wait Until Element Is Visible"
    #   3. Args: id=button, 10s
    #   4. Execute to check if element appears
```

### Example 3: Variable Inspection

```robot
*** Test Cases ***
Variable Test
    ${result}=    Calculate Something
    # Pause and check Variable Inspector
    # See ${result} value before proceeding
    Should Be Equal    ${result}    expected_value
```

## Usage

### Starting the Debugger

Run your tests with rfdb as a listener:

```bash
robot --listener rfdb your_test.robot
```

The debugger GUI opens automatically when a test fails.

### Keyboard Shortcuts
- **Ctrl+Q**: Emergency exit (force close debugger)

### Best Practices

1. **Use Search**: When running custom keywords, use the search box to quickly find keywords in large libraries

2. **Monitor Variables**: Switch to Variable Inspector tab during pauses to check test state

3. **Retry Failures**: Instead of re-running entire test suite, retry failed keywords directly

4. **Check Call Stack**: Use "View Call Stack" to understand where you are in nested keyword execution

5. **Performance**: Debugger limits logs to 1000 lines and failure logs to 500 lines for VDI/slow environments

## Configuration

Edit these constants in `gui.py` if needed:

```python
MAX_LOG_LINES = 1000              # Main log size
MAX_FAILURE_LOG_LINES = 500       # Failure log size  
VARIABLE_REFRESH_DELAY_MS = 1000  # Variable refresh rate (ms)
```

## Troubleshooting

### Debugger doesn't pause
- Check that the library is imported in your test Settings
- Verify Robot Framework version compatibility (v7.1.1+)

### Keywords not loading
- Library loads lazily when first needed
- Click "Refresh" to force reload library keywords
- Check library import statements in your test

### GUI freezes
- Press Ctrl+Q for emergency exit
- Keywords timeout automatically after 30 seconds
- Check VDI performance settings if running remotely

### Variables not updating
- Variables only refresh during active test execution
- Switch to Variable Inspector tab to trigger refresh
- Check that test hasn't completed yet
