workbench - MUnit creating a hierarchy of TestSuites


I would like to create a hierarchy of TestSuites. However it appears that it is not possible to call a TestSuite from another TestSuite. So before I go and reinvent the wheel, I thought I would see how others have done (or would) accomplish this.



Details of what I am trying to accomplish


I have grouped packages (and their tests) that perform like functionality by directory. For illustrative purposes lets say I have three subdirectories: importers, manipulators, and processes. I have a TestSuite in each subdirectory named TestAll.mt . I also have one in the top level directory called TestAll.mt that I would like to have call the TestAll.mt in the three subdirectories.



I would like to be able to run the test suites at both the subdirectory and top levels. Running the test suite at the subdirectory level would only run the particular subset of tests, while running the test suite at the top level would run the test suites in all the subdirectories.


I would like to avoid having to add an entry for a particular test to both the subdirectory and top level test suites.


A bonus would be if the top level test suite auto discovered the test suites in the subdirectories (not having to specify the subdirectories in the root test suite), but that is not crucial.


Update



Attempt #1 -- Make a list of .mt files in each of the sub TestAll.mt s. If the top level TestAll.mt is called, the sub levels' lists would be appended to the top level's list and then that list would be supplied to TestSuite. If a sub level's TestAll.mt is called, its list would be supplied as the argument to TestSuite.


Result: Failure


From Workbench, adding any expression to a .mt that contains TestSuite appears to cause none of the tests to run.


x=1;
TestSuite[

    {
        "Test1.mt",
        "Test2.mt"
    }
]

From a notebook, TestSuite shows up in command completion, but does not show up in the MUnit package usage info. Executing the following:


TestSuite[
 {
  "/pathToTests/Test1.mt",

  "/pathToTests/Test2.mt"
  }
 ]

Results in:


TestSuite[{"/pathToTests/Test1.mt", "/pathToTests/Test2.mt"}]

Searched the MUnit package files for TestSuite, no hits.


cd "/Applications/Wolfram Workbench.app/configuration/org.eclipse.osgi/bundles/214/1/.cp/MathematicaSourceVersioned/Head/MUnit"
find . -name "*.m" -print -exec grep TestSuite {} \;



Attempt #2 -- Roll my own TestSuite ...

plotting - Plot 4D data with color as 4th dimension

I have a list of 4D data (x position, y position, amplitude, wavelength). I want to plot x, y, and amplitude on a 3D plot and have the color of the points correspond to the wavelength. I have seen many examples using functions to define color but my wavelength cannot be expressed by an analytic function. Is there a simple way to do this? Answer Here a another possible way to visualize 4D data: data = Flatten[Table[{x, y, x^2 + y^2, Sin[x - y]}, {x, -Pi, Pi,Pi/10}, {y,-Pi,Pi, Pi/10}], 1]; You can use the function Point along with VertexColors . Now the points are places using the first three elements and the color is determined by the fourth. In this case I used Hue, but you can use whatever you prefer. Graphics3D[ Point[data[[All, 1 ;; 3]], VertexColors -> Hue /@ data[[All, 4]]], Axes -> True, BoxRatios -> {1, 1, 1/GoldenRatio}]

plotting - Filling between two spheres in SphericalPlot3D

Manipulate[ SphericalPlot3D[{1, 2 - n}, {θ, 0, Pi}, {ϕ, 0, 1.5 Pi}, Mesh -> None, PlotPoints -> 15, PlotRange -> {-2.2, 2.2}], {n, 0, 1}] I cant' seem to be able to make a filling between two spheres. I've already tried the obvious Filling -> {1 -> {2}} but Mathematica doesn't seem to like that option. Is there any easy way around this or ... Answer There is no built-in filling in SphericalPlot3D . One option is to use ParametricPlot3D to draw the surfaces between the two shells: Manipulate[ Show[SphericalPlot3D[{1, 2 - n}, {θ, 0, Pi}, {ϕ, 0, 1.5 Pi}, PlotPoints -> 15, PlotRange -> {-2.2, 2.2}], ParametricPlot3D[{ r {Sin[t] Cos[1.5 Pi], Sin[t] Sin[1.5 Pi], Cos[t]}, r {Sin[t] Cos[0 Pi], Sin[t] Sin[0 Pi], Cos[t]}}, {r, 1, 2 - n}, {t, 0, Pi}, PlotStyle -> Yellow, Mesh -> {2, 15}]], {n, 0, 1}]

plotting - Mathematica: 3D plot based on combined 2D graphs

I have several sigmoidal fits to 3 different datasets, with mean fit predictions plus the 95% confidence limits (not symmetrical around the mean) and the actual data. I would now like to show these different 2D plots projected in 3D as in but then using proper perspective. In the link here they give some solutions to combine the plots using isometric perspective, but I would like to use proper 3 point perspective. Any thoughts? Also any way to show the mean points per time point for each series plus or minus the standard error on the mean would be cool too, either using points+vertical bars, or using spheres plus tubes. Below are some test data and the fit function I am using. Note that I am working on a logit(proportion) scale and that the final vertical scale is Log10(percentage). (* some test data *) data = Table[Null, {i, 4}]; data[[1]] = {{1, -5.8}, {2, -5.4}, {3, -0.8}, {4, -0.2}, {5, 4.6}, {1, -6.4}, {2, -5.6}, {3, -0.7}, {4, 0.04}, {5, 1.0}, {1, -6.8}, {2, -4.7}, {3, -1....
