Test case for draw a line chart.

C#
Copy
lLineChart = new LineChart();

//* draws chart *
lLineChart.Create(lTestFile, lXAxis, lYAxis, lPoints, LineChartType.Line,
                  pViewXAxis: SIC.Draw.AxisDisplay.Labels,
                  pViewYAxis: SIC.Draw.AxisDisplay.Labels,
                  pBorderSpacing: 55,     //* correction for label view *
                  pXLabelSpacing: 27,     //* correction for label view *
                  pShowScaling: false,    //* test case: scaling then on true *
                  pXLabel: "X Label",
                  pYLabel: "Y Label"
                  );

Test Project

  1. Create a test project (SOWI Test Project template) or go to exists a test project.

  2. Add assembly SIC.Draw as a reference in the project

Test Unit

  1. Create a test unit (project item template called SOWITestUnit or go to exists test unit

  2. Go to tasks token UNDONE. For this example, the lines can be deleted.

Test Case

  1. Create a test case (code snippet scsTestCase)

  2. Implement section "Preparation"

    C#
    Copy
    #region --- Preparation ---
this.Log.WriteTitle("TEST PREPARATION");

this.Log.Write("Test variable...");

SIC.Draw.LineChart lLineChart = null;
List<SIC.Draw.Axis> lXAxis = null;
List<SIC.Draw.Axis> lYAxis = null;
List<SIC.Draw.Point> lPoints = null;
string lTestFile = this.ResultDirectory + this.Log.Name;

//---
// TOSET: test values and correct result values

//* x axis *
lXAxis = new List<SIC.Draw.Axis>();
lXAxis.Add(new SIC.Draw.Axis(10, "left"));
lXAxis.Add(new SIC.Draw.Axis(20, "middle"));
lXAxis.Add(new SIC.Draw.Axis(30, "right"));
lXAxis.Add(new SIC.Draw.Axis(25, "between"));   //* test case: correct sorted *

//* y axis *
lYAxis = new List<SIC.Draw.Axis>();
lYAxis.Add(new SIC.Draw.Axis(30, "up"));
lYAxis.Add(new SIC.Draw.Axis(20, "middle"));
lYAxis.Add(new SIC.Draw.Axis(10, "down"));
lYAxis.Add(new SIC.Draw.Axis(15, "between"));   //* test case: correct sorted *

//* chart values *
lPoints = new List<SIC.Draw.Point>();
lPoints.Add(new SIC.Draw.Point(10, 10));
lPoints.Add(new SIC.Draw.Point(13, 18));
lPoints.Add(new SIC.Draw.Point(20, 20));
lPoints.Add(new SIC.Draw.Point(25, 22));
lPoints.Add(new SIC.Draw.Point(30, 30));

//---

string lTestFileResult = "";

//* protocol test preparation *
this.Log.Write("Test file name", "\t" + lTestFile);
lXAxis.ForEach(delegate (SIC.Draw.Axis pAxis)
    {
        this.Log.Write("X Axis \t Value: \t" + pAxis.Value.ToString() + "\t Label: " + pAxis.Label);
    });
lYAxis.ForEach(delegate (SIC.Draw.Axis pAxis)
    {
        this.Log.Write("Y Axis \t Value: \t" + pAxis.Value.ToString() + "\t Label: " + pAxis.Label);
    });
lPoints.ForEach(delegate (SIC.Draw.Point pPoint)
    {
        this.Log.Write("Point  \t X:     \t" + pPoint.X.ToString() + "\t Y: " + pPoint.Y.ToString());
    });
this.Log.Write("Test prepared");
#endregion

  3. Implement section Execution

    C#
    Copy
    #region --- Execution ---
this.Log.WriteTitle("TEST EXECUTION");
this.Log.Write("Crate Line Chart...");
this.Log.TestStart();
try
{
    lLineChart = new LineChart();

    //* draws chart *
    lLineChart.Create(lTestFile, lXAxis, lYAxis, lPoints, LineChartType.Line,
                      pViewXAxis: SIC.Draw.AxisDisplay.Labels,
                      pViewYAxis: SIC.Draw.AxisDisplay.Labels,
                      pBorderSpacing: 55,     //* correction for label view *
                      pXLabelSpacing: 27,     //* correction for label view *
                      pShowScaling: false,    //* test case: scaling then on true *
                      pXLabel: "X Label",
                      pYLabel: "Y Label"
                      );

    lTestFileResult = lLineChart.File;
}
catch (Exception ex)
{
    this.Log.IsTrue(ref ex);
}
this.Log.TestEnd();

//* protocol test execution *
this.Log.Write("Test result file name", lTestFileResult);
this.Log.Write("Test executed");
#endregion

  4. Implement section Test Analysis

    C#
    Copy
    #region --- Analysis ---
this.Log.WriteTitle("TEST ANALYSIS");

//* conditions *
this.Log.IsTrue(lXAxis != null, "X axis object is null", "X axis object OK");
this.Log.IsTrue(lYAxis != null, "Y axis object is null", "Y axis object OK");
this.Log.IsTrue(lPoints != null, "Points object is null", "Points object OK");

this.Log.IsTrue(lLineChart != null, "Line Chart object is null", "Line Chart object OK");
this.Log.IsTrue(System.IO.File.Exists(lTestFileResult), "No exists test file. Result value: " + lTestFileResult.ToString(), "Result file OK");

//* write result of conditions *
this.Log.Result();
#endregion
