Detailed Description

Manages isolated test databases for parallel test execution.

This class provides utilities for creating and destroying unique test databases for each test process. This allows multiple test processes to run concurrently without interference.

Each test database is created from the oresdb_template database, which must be pre-configured with the full schema.

Member Function Documentation

generate_test_database_name()

std::string generate_test_database_name ( )

static

Generates a unique database name for this test process.

The database name is based on the process ID and a random suffix to ensure uniqueness: oresdb_test_{pid}_{random}

Returns

A unique database name string

Here is the caller graph for this function:

create_test_database()

void create_test_database ( const std::string &  db_name )

static

Creates a test database from the oresdb_template.

This method connects to the postgres database (admin database) and executes CREATE DATABASE with the template parameter.

Parameters

db_name

The name of the database to create

Exceptions

std::runtime_error

if database creation fails

Here is the caller graph for this function:

drop_test_database()

void drop_test_database ( const std::string &  db_name )

static

Drops the test database.

This method connects to the postgres database and executes DROP DATABASE. It terminates any active connections first.

Parameters

db_name

The name of the database to drop

Here is the caller graph for this function:

set_test_database_env()

void set_test_database_env ( const std::string &  db_name )

static

Sets the TEST_ORES_DB_DATABASE environment variable.

This ensures that database_fixture and all tests use the isolated test database.

Parameters

db_name

The database name to set
