Introduction

The release of platform-specific toolboxes on CI is a significant milestone in the development of TopoToolbox. To ensure that these toolboxes work seamlessly on different platforms, it is essential to conduct thorough testing. In this article, we will guide you through the process of testing the release toolboxes, focusing on the functionality of regular TopoToolbox functions, MEX interfaces to libtopotoolbox, and documentation.

Testing the Toolboxes

To begin testing the toolboxes, you need to download the mltbx file associated with your operating system and architecture. This file can be found on the GitHub repository: https://github.com/TopoToolbox/topotoolbox3/releases/tag/latest. Once you have downloaded the file, open it in MATLAB to install the toolbox.

Testing Regular TopoToolbox Functions

The first step in testing the toolboxes is to verify that regular TopoToolbox functions work as expected. This includes checking the functionality of various tools, such as:

Terrain Analysis: Verify that terrain analysis functions, such as dem2topo and topo2dem, produce accurate results.
Hydrological Analysis: Check that hydrological analysis functions, such as streamorder and catchment, function correctly.
Geological Analysis: Verify that geological analysis functions, such as geology and geology2topo, produce accurate results.

To test these functions, you can use the following code:

% Load a sample DEM
DEM = topotoolbox3.loadSampleDEM();

% Perform terrain analysis
topo = dem2topo(DDEM);

% Perform hydrological analysis
streamorder(topo);

% Perform geological analysis
geology(topo);

Testing MEX Interfaces to Libtopotoolbox

The MEX interfaces to libtopotoolbox are a crucial component of TopoToolbox. To test these interfaces, you need to use the following code:

% Check if libtopotoolbox is available
haslibtopotoolbox

% Fill sinks in a DEM using libtopotoolbox
fillsinks(DEM, uselibtt=true);

% Fill sinks in a DEM without using libtopotoolbox
fillsinks(DEM, uselibtt=false);

Compare the results of the two functions to ensure that they produce identical results.

Testing Documentation

The documentation of TopoToolbox is essential for users to understand the functionality of the toolbox. To test the documentation, you can use the following code:

% Display the documentation for a specific function
help dem2topo

Verify that the documentation is accurate and up-to-date.

Conclusion

Testing the release toolboxes is a critical step in ensuring that they work seamlessly on different platforms. By following the steps outlined in this article, you can verify that regular TopoToolbox functions, MEX interfaces to libtopotoolbox, and documentation are working correctly. If you encounter any issues during testing, please add a comment to this issue so that we can keep track of things.

Troubleshooting

If you encounter any issues during testing, please follow these steps:

Check the documentation: Verify that the documentation is accurate and up-to-date.
Check the code: Review the code to ensure that it is correct and up-to-date.
Check the dependencies: Verify that all dependencies are installed and up-to-date.
Check the platform: Verify that the issue is not specific to a particular platform.

If none of these steps resolve the issue, please add a comment to this issue so that we can investigate further.

Future Development

The testing of release toolboxes is an ongoing process. As new features are added to TopoToolbox, it is essential to test them thoroughly to ensure that they work seamlessly on different platforms. In the future, we plan to:

Improve the testing framework: Develop a more comprehensive testing framework to ensure that all components of TopoToolbox are thoroughly tested.
Add more test cases: Add more test cases to ensure that all scenarios are covered.
Improve the documentation: Improve the documentation to ensure that it is accurate and up-to-date.

By following these steps, we can ensure that TopoToolbox continues to be a reliable and accurate tool for terrain analysis.
