Robot Framework Database Library

The Database Library for Robot Framework allows you to query a database and verify the results. It requires an appropriate Python module to be installed separately - depending on your database, like e.g. oracledb or pymysql.

The library consists of some keywords designed to perform different checks on your database. Here you can find the keyword docs.

Requirements

  • Python
  • Robot Framework
  • Python database module you're going to use - e.g. oracledb

Installation

pip install robotframework-databaselibrary

Usage examples

Basic usage

*** Settings ***
Library       DatabaseLibrary
Test Setup    Connect To My Oracle DB

*** Keywords ***
Connect To My Oracle DB
    Connect To Database
    ...    oracledb
    ...    dbName=db
    ...    dbUsername=my_user
    ...    dbPassword=my_pass
    ...    dbHost=127.0.0.1
    ...    dbPort=1521

*** Test Cases ***
Person Table Contains Expected Records
    ${output}=    Query    select LAST_NAME from person
    Length Should Be    ${output}    2
    Should Be Equal    ${output}[0][0]    See
    Should Be Equal    ${output}[1][0]    Schneider

Person Table Contains No Joe
    ${sql}=    Catenate    SELECT id FROM person
    ...                    WHERE FIRST_NAME= 'Joe'    
    Check If Not Exists In Database    ${sql}

Handling multiple database connections

*** Settings ***
Library          DatabaseLibrary
Test Setup       Connect To All Databases
Test Teardown    Disconnect From All Databases

*** Keywords ***
Connect To All Databases
    Connect To Database    psycopg2    db    db_user    pass    127.0.0.1    5432
    ...    alias=postgres
    Connect To Database    pymysql    db    db_user    pass    127.0.0.1    3306
    ...    alias=mysql

*** Test Cases ***
Using Aliases
    ${names}=    Query    select LAST_NAME from person    alias=postgres
    Execute Sql String    drop table XYZ                  alias=mysql

Switching Default Alias
    Switch Database    postgres
    ${names}=    Query    select LAST_NAME from person
    Switch Database    mysql
    Execute Sql String    drop table XYZ

See more examples in the folder tests.

Database modules compatibility

The library is basically compatible with any Python Database API Specification 2.0 module.

However, the actual implementation in existing Python modules is sometimes quite different, which requires custom handling in the library. Therefore there are some modules, which are "natively" supported in the library - and others, which may work and may not.

Python modules currently "natively" supported

Oracle

  • oracledb
    • Both thick and thin client modes are supported - you can select one using the driverMode parameter.
    • However, due to current limitations of the oracledb module, it's not possible to switch between thick and thin modes during a test execution session - even in different suites.
  • cx_Oracle

MySQL

PostgreSQL

MS SQL Server

SQLite

Teradata

IBM DB2

ODBC

Kingbase

  • ksycopg2
