db-autotest

DB Database test automation. This python package allows to create database object structure and load data from database.

One further option is to print, save data as YAML file, another is to use retrieved object in data comparissons or new database object creation.

DB structure as object in Python

Better explanation is code example from c_m_table.py.

class C_M_Table(object):

    def __init__(self):

        # ==================================== m_table ===============================
        self.t_m_table = M_Entity(m_object_detail(), m_object_detail_r(), name='table')
        
        # ==================================== m_object ===============================
        self.t_m_object = M_Entity(m_object(), m_object_r(), name='object')

        self.r_m_object_table = M_Relation(self.t_m_object, self.t_m_table)
        self.s_m_object = M_Structure(self.t_m_object, M_StructureType.PARENT)

        # ==================================== m_column ===============================
        self.t_m_column = M_Entity(m_column(), m_column_r(), name='column')
        self.t_m_column.sortFunc = columnSortFunc.__get__(self.t_m_column)

        self.r_m_table_column = M_Relation(self.t_m_table, self.t_m_column)
        self.s_m_column = M_Structure(self.t_m_column, M_StructureType.CHILD)

        # ==================================== m_index ===============================
        self.t_m_index = M_Entity(m_object_detail(), m_object_detail_r(), name='index')

        self.r_m_table_index = M_Relation(self.t_m_table, self.t_m_index)
        self.r_m_table_index.parent_ids = [m_object_detail().m_object_id, m_object_detail().m_version_id]
        self.r_m_table_index.child_ids = [m_object_detail().idx_table_id, m_object_detail().m_version_id]
        self.s_m_index = M_Structure(self.t_m_index, M_StructureType.CHILD)

        # ==================================== m_idx_column ===============================
        self.t_m_idx_column = M_Entity(m_column(), m_column_r(), name='idx_column')
        self.t_m_idx_column.sortFunc = columnSortFunc.__get__(self.t_m_idx_column)

        self.r_m_idx_column = M_Relation(self.t_m_index, self.t_m_idx_column)
        self.s_m_idx_column = M_Structure(self.t_m_idx_column, M_StructureType.CHILD)        
        self.s_m_index.child.append([self.s_m_idx_column, self.r_m_idx_column])

        # ==================================== s_m_table ===============================
        self.s_m_table = M_Structure(self.t_m_table)
        self.s_m_table.parent.append([self.s_m_object, self.r_m_object_table])
        self.s_m_table.child.append([self.s_m_column, self.r_m_table_column])
        self.s_m_table.child.append([self.s_m_index, self.r_m_table_index])

        self.c_main = M_Class(self.s_m_table)


def columnSortFunc(self, e):
    return e[get_column_i(self, m_column().sort)]
