A mock for oracledb Node.js module 

Usage

``js
import createMock from '@natlibfi/oracledb-mock';

const oracledb = createMock();

oracledbMock._execute([
{
queryPattern: /^SELECT * from foobar$/,
results: [
{ foo: 'bar' }
]
}
]);

await operate(oracledbMock);

oracledbMock._clear();

async function operate(oracledb) {
const connection = await oracledb.getConnection();
const {resultSet} = await connection.execute('SELECT * from foobar');
const row = await resultSet.getRow();
// do something with {foo: 'bar'}
return connection.close();
}
`


Mocking queries


The _execute method initializes the mock with expected queries and their results. An array of object is passed to the _execute method and the array is iterated for matching results. The following parameters are supported
- queryPattern: A RegExp object which the query is tested against. Defaults to .*`.
- expectedArgs: An optional object which, if present, must be equal to the arguments passed to the execute-call of the connection.
- results: An array of results represented as object (Column names are the properties).
