Water Refill Station Checks with Manual Software Testing: A 2027 Project Guide

A convincing Manual Software Testing portfolio project explains the result as well as showing it. Here, a campus facilities volunteer asks: How much completed inspection time is recorded by station? You will build a risk-based test report and follow the relevant records from a small fixture to an independently checked answer.

This is a 2027 study-edition project brief. All example records and operational situations are fictional. Start with basic Manual Software Testing knowledge, the ability to inspect structured data and a local practice environment. The complete first version should answer the stated question before adding accounts, real integrations or additional screens.

Define the project rule

Inspection minutes record completion of a checklist only. The exercise does not assess water safety or replace laboratory testing; cancelled inspections do not count as completed checks. For this exercise, one row represents one station_check. The stable key is record_id; station_name is the grouping or filtering label. The numeric inspection_minutes field uses minutes. Accepted states are planned, completed, cancelled.

The summary selects status completed and applies sum to the selected numeric values. Keep this definition visible in the interface, response or report so another learner can reproduce it. Use positive finite values in the starter fixture and define any future zero or missing-value policy explicitly.

Choose the Manual Software Testing approach

Translate the project rule into observable behaviour before opening the interface. Write a small set of high-value examples with input, action and expected outcome. Explore boundaries and recovery rather than counting repetitive test cases. A useful defect report gives a reproducible setup, actual result, expected result and evidence that another person can verify.

The three design decisions to explain in your project notes are:

• Observable acceptance criteria. Apply this choice to station_check records and explain its effect on inspection_minutes.
• Boundary and state-transition tests. Apply this choice to station_check records and explain its effect on inspection_minutes.
• Reproducible defect evidence. Apply this choice to station_check records and explain its effect on inspection_minutes.

Work through a small sample

The three records below are deliberately small enough to inspect by hand. They are a compact specification for the data shape and expected result, and can later be expanded into a larger synthetic fixture.

[
  {
    "record_id": "water-refill-checks-01",
    "station_name": "Library Station",
    "inspection_minutes": 25,
    "status": "completed",
    "recorded_on": "2027-01-04"
  },
  {
    "record_id": "water-refill-checks-02",
    "station_name": "Workshop Station",
    "inspection_minutes": 40,
    "status": "planned",
    "recorded_on": "2027-01-05"
  },
  {
    "record_id": "water-refill-checks-03",
    "station_name": "Main Hall Station",
    "inspection_minutes": 15,
    "status": "completed",
    "recorded_on": "2027-01-06"
  }
]

Only the first and third records match completed. Their inspection_minutes values are 25 and 15; the full-fixture result is 40 minutes, with 2 matching records. Selecting station_name = Library Station leaves the first record, so the result becomes 25 minutes, with 1 match. This provides two independent checks for the filter and aggregation.

The full-fixture output contract is:

{
  "matching_count": 2,
  "operation": "sum",
  "value": 40,
  "unit": "minutes"
}

Check the result by station_name

The overall figure answers the all-records version of the question. Grouping by station_name produces the following separate expectations, using the same completed rule. The middle group has a record in the source fixture but no qualifying observation.

Use this breakdown when answering the group-level question. Compare like-for-like units and keep the matching count visible, especially for averages. A different filter changes which records enter the calculation; it does not change the meaning of the metric.

The code blocks describe sample data and an expected result. Implement the surrounding feature using the installed version of your chosen tools, then save the actual run evidence separately from these expectations.

Build the feature in three passes

1. Turn the rule into assertions

Write an observable expectation for completed station_check records and the sum of inspection_minutes. Include the selected station_name and minutes label in the expected result. Define a clean setup so each case starts from known data.

2. Cover a change and a rejected input

Run the supplied scenario-specific acceptance check, then try a missing station_name, an invalid inspection_minutes and a repeated identifier. Inspect both the returned response and resulting state. A rejection should explain the correction and preserve valid existing records.

3. Make the evidence reproducible

Record exact inputs, actions, expected outcomes and actual outcomes. Automate checks only at the boundary supported by the chosen tool. Keep fixtures independent and capture useful failure evidence without replacing a precise assertion with a screenshot alone.

Find the mistake before polishing the result

A useful defect to introduce deliberately is: A completed checklist is described as proof of water quality. First reproduce it against the fixture, then identify the smallest rule or state transition that explains the mismatch. Fix that boundary and rerun the full-fixture and selected-label examples. This creates a stronger explanation than changing several unrelated parts until the screen looks right.

The scenario-specific acceptance check is: Keep the measure explicitly about recorded inspection activity. Preserve before-and-after evidence. Add a missing station_name, a negative inspection_minutes, an unrecognised status and a duplicate record_id as separate invalid cases. Define the rejection or duplicate-handling policy before testing, and verify that invalid input does not silently change valid existing records.

Check the Manual Software Testing concerns as well:

• A passed case needs a recorded outcome.
• A failure needs reproducible steps.
• Test data must not depend on a previous tester's run.

For an empty filter match, the expected sum value is 0. Keep matching_count at zero. This distinction prevents an empty dataset from being interpreted as a measured observation.

Explain the finished work in a portfolio

Show the campus facilities volunteer question, the record definition and the expected calculation first. Then demonstrate a station_name filter and the acceptance check. Include the fixture, setup instructions, chosen tool versions, actual test output and one remaining limitation in the repository. If you show a screenshot, pair it with the input that produced it. Another learner should be able to repeat the same result from a clean checkout.

For a focused extension, add a second station_name selection and compare the two groups using the same rule. Specify how missing groups appear and keep the original fixture as a regression case. Expand scope only after the current calculation, state handling and recovery path remain understandable.

Questions learners often ask

Which station_check records belong in the result?

Select records whose status is exactly completed and that satisfy the chosen station_name filter. Other states remain in the source data and can have separate summaries. Follow the domain rule above when a record changes state.

What should happen when no records match?

Return a zero total with a matching count of zero and a clear empty-result message. Keep the applied filter visible so the user can change it. Avoid using a loading indicator for a completed request that simply has no matching data.

How can I prove the inspection_minutes result is correct?

Reconcile the first and third sample records, then repeat the calculation for Library Station alone. Save both expected and actual outputs, and rerun the scenario-specific acceptance check after making a change.
