Introduction

Robocop is a tool that performs static code analysis of Robot Framework code.

It uses official Robot Framework parsing API to parse files and run number of checks, looking for potential errors or violations to code quality standards.

Hosted on GitHub

Documentation

Full documentation available here.

Values

Original RoboCop - a fictional cybernetic police officer - was following 3 prime directives which also drive the progress of Robocop linter:

First Directive: Serve the public trust

Which lies behind the creation of the project - to serve developers and testers as a tool to build applications they can trust

Second Directive: Protect the innocent

The innocent testers and developers have no intention to produce ugly code but sometimes, you know, it just happens, so Robocop is there to protect them

Third Directive: Uphold the law

Following the coding guidelines established in the project are something very important to keep the code clean, readable and understandable by others and Robocop can help to uphold the law

Requirements

Python 3.6+ and Robot Framework 3.2.1+.

Installation

You can install Robocop simply by running:

pip install robotframework-robocop

Usage

Robocop runs by default from the current directory and it discovers supported files recursively. You can simply run:

robocop

All command line options can be displayed in help message by executing:

robocop -h

Example Output

Executing command:

robocop --report rules_by_error_type tests\test.robot

Will result in following output:

C:\OCP_project\tests\test.robot:7:0 [W] 0509 Section is empty
C:\OCP_project\tests\test.robot:22:0 [E] 0801 Multiple test cases with name "Simple Test" in suite
C:\OCP_project\tests\test.robot:42:0 [E] 0810 Both Task(s) and Test Case(s) section headers defined in file
C:\OCP_project\tests\test.robot:48:0 [W] 0302 Keyword name should be capitalized
C:\OCP_project\tests\test.robot:51:13 [I] 0606 This tag is already set by Force Tags in suite settings

Found 5 issue(s): 2 WARNING(s), 2 ERROR(s), 1 INFO(s).

Main features

including/excluding rules from command line with the support for glob patterns:
```
--include *missing* -i W0507 --exclude rule,rule2 -e *doc*
```

disabling rules directly from source code

Ignoring rules in one line:

This is Keyword  # robocop: disable=not-capitalized-keyword-name

Ignoring all rules or selected ones:

Log  ${var}
Log  ${var}  # robocop: disable
log  ${var}  # robocop: disable=0301,0302

Ignoring whole blocks or even files:

# robocop: disable=unnecessary-default-tags,0102
*** Settings ***
Library  RobotLibrary.py

# robocop: enable=0102

filtering out all rules below given severity level:
```
--threshold E
```

customized format of output message:

--format "{source}:{line}:{col} [{severity}] {rule_id} {desc}"

configurable return status for every severity level:
```
--configure return_status:quality_gate:E=2:W=39
```

generating customized reports:

--reports rules_by_id,rules_by_error_type

Issues by ids:
W1007 (uneven-indent)                : 5
E0904 (nested-for-loop)              : 4
W0302 (not-capitalized-keyword-name) : 4

Found 12 issue(s): 9 WARNING(s), 4 ERROR(s).

configurable lint rules:

--configure 0507:line_length:100 -c uneven-indent:severity:W

external rules support:

--ext_rules path/to/your/rules.py -rules supports_many_paths.py

output redirection to file:
```
--output robocop.log
```
loading arguments from file:
```
--argumentfile jenkins_args.txt
```
configurable scanned filetypes:
```
--filetypes .txt,.rst
```

paths matching pattern can be ignored:

--ignore *.robot,resources/* --ignore special_file.txt
