Design Patterns for Database API Testing 4: REF Cursor Getter

Last October I gave a presentation on database unit testing with utPLSQL, Oracle Unit Testing with utPLSQL. I mentioned design patterns as a way of reducing the effort of building unit tests and outlined some strategies for coding them effectively.

In the current set of articles, I develop the ideas further, starting from the idea that all database APIs can be considered in terms of the axes:

  • direction (i.e. getter or setter, noting that setters can also 'get')
  • mode (i.e. real time or batch)

For each cell in the implied matrix, I construct an example API (or view) with specified requirements against Oracle's HR demo schema, and use this example to construct a testing program with appropriate scenarios as a design pattern. Concepts and common patterns and anti-patterns in automated API testing are discussed throughout, and these are largely independent of testing framework used. However, the examples use my own lightweight independent framework that is designed to help avoid many API testing anti-patterns. The code is available on GitHub here, BrenPatF/trapit_oracle_tester, and includes both framework and design pattern examples.

Behind the four examples, there is an underlying design pattern that involves wrapping the API call in a 'pure' procedure, called once per scenario, with the output 'actuals' array including everything affected by the API, whether as output parameters, or on database tables, etc. The inputs are also extended from the API parameters to include any other effective inputs. Assertion takes place after all scenarios and is against the extended outputs, with extended inputs also listed. This concept of the 'pure' function, central to Functional Programming, has important advantages in automated testing. I explained the concepts involved in a presentation at the Oracle User Group Ireland Conference in March 2018:

The Database API Viewed As A Mathematical Function: Insights into Testing

The previous example is here: Design Patterns for Database API Testing 3: Batch Loading of Flat Files. This fourth example covers getting data in real time via a REF cursor, such as would often be used as the source for a web service.

Requirement Summary

Modern Oracle SQL is very powerful and can apply complex logic within a single statement, reducing the need for more complex procedural code. In order to show how to API test SQL that might be used in a batch getter module, we previously devised a test view, HR_Test_V, having a range of features that we might want to test in general. We can use similar SQL to demonstrate API testing of a real time getter procedure that might be used by a web service, where reference cursors are often used as output parameters. The following list of features to test is taken, in slightly modified form, from Design Patterns for Database API Testing 2: Views 1 - Design

  • Inner joins suppress driving records where there is no joining record
  • Outer joins return driving records where there is no joining record
  • Analytic functions that partition by some key, and return aggregates on the returned record set
  • Functions based on aggregates over records that include those not in the returned record set
  • Constraints based on aggregates over records that include those not in the returned record set
  • Constraints on column values

The SQL functionality can be described in words as:

  • Selected values
    • Employee name, department name, and salary
    • Manager's name
    • Ratio of employee's salary to the department average (returned employees only)
    • Ratio of employee's salary to the average salary of all employees
  • Constraints
    • Exclude employees in job 'AD_ASST'
    • Return employees for a department passed as a bind parameter
    • Do not return any records if the total salary of all employees is below 1600
  • Outer join
    • Include employees both with and without a manager

The REF cursor SQL is:

  WITH all_emps AS (
        SELECT Avg (salary) avg_sal, SUM (salary) sal_tot_g
          FROM employees e
)
SELECT e.last_name, d.department_name, m.last_name manager, e.salary,
       Round (e.salary / Avg (e.salary) OVER (PARTITION BY e.department_id), 2) sal_rat,
       Round (e.salary / a.avg_sal, 2) sal_rat_g
  FROM all_emps a
 CROSS JOIN employees e
  JOIN departments d
    ON d.department_id = e.department_id
  LEFT JOIN employees m
    ON m.employee_id = e.manager_id
 WHERE e.job_id != 'AD_ASST'
   AND a.sal_tot_g >= 1600
   AND d.department_id = :1

Notes on API Testing REF Cursor Procedures

  • A new utility function has been added to Utils_TT, Cursor_to_Array, that converts an open reference cursor to a delimited list of strings (created from an initial stand-alone procedure: A Utility for Reading REF Cursors into a List of Delimited Strings)
  • Using this utility, very little code needs to be written once the test data has been set up: One call to return the reference cursor, and a second to return the actual values in a list, to be passed at the end in a single call to the library results checker

Design Pattern Groups

The API testing framework is centred around the concept of input and output groups, representing the data sets that respectively form the inputs to, and outputs from, the program. The records in each group are printed by the framework with column headers for each scenario. These groups are identified by the developer, and in this case they are as noted below.

Input Groups

  • Employees Table
  • Department Parameter

Output Groups

  • Select results
  • Timing of average call

Test Scenarios

The scenario descriptions start with a data set code, followed by a verbal description.

  1. DS-1, testing inner, outer joins, analytic over dep, and global ratios with 1 dep (10) - pass dep 10
  2. DS-2, testing same as 1 but with extra emp in another dep (20) - pass dep 10
  3. DS-2, as second scenario, but - pass dep 20
  4. DS-2, as second scenario, but - pass null dep
  5. DS-3, Salaries total 1500 (< threshold of 1600, so return nothing) - pass dep 10

Notes on setup section

  • c_dataset_3lis contains the data for all data sets indexed by (data set, record, field)
  • Setup_Array is called once to do some setup on the arrays
  • Setup_DB is called for a single data set at a time in each scenario
  • Description of the data set is contained in the array and printed out
  • Data set is printed out in tabular format. In the current version of the utility code, this is not strictly necessary, because all the input data is printed out before the outputs

  • Main section loops over the scenarios calling Purely_Wrap_API
  • Is_Deeply is called to do all the assertions within nested loops, then print the results
