HTML report of test results

When running tests in Julia, it is often useful to generate an HTML report of the test results. This report can provide a summary of the tests that were run, including information such as the number of tests passed and failed, as well as any error messages or stack traces that were generated during the test run.

In this article, we will explore three different ways to generate an HTML report of test results in Julia. Each approach will be presented with sample code and will be divided into different sections using

tags.

Option 1: Using the HTMLBuilder package

The HTMLBuilder package provides a convenient way to generate HTML code in Julia. To use this package, you can start by installing it using the following command:

“`julia
using Pkg
Pkg.add(“HTMLBuilder”)
“`

Once the package is installed, you can use it to generate an HTML report of test results. Here is a sample code that demonstrates how to do this:

using HTMLBuilder

function generate_html_report(test_results)
    html = HTML()
    body = Body()

    # Add a header
    header = H1("Test Results")
    append!(body, header)

    # Add a summary of the test results
    summary = P("Total tests: ", length(test_results))
    append!(body, summary)

    # Add individual test results
    for result in test_results
        test_name = result["name"]
        test_status = result["status"]
        test_message = result["message"]

        test_result = P("Test: ", test_name)
        append!(body, test_result)

        if test_status == "pass"
            test_result_status = P("Status: Passed")
        else
            test_result_status = P("Status: Failed")
            test_result_message = P("Error message: ", test_message)
            append!(body, test_result_message)
        end

        append!(body, test_result_status)
    end

    append!(html, body)
    return html
end

# Sample test results
test_results = [
    Dict("name" => "Test 1", "status" => "pass"),
    Dict("name" => "Test 2", "status" => "fail", "message" => "Assertion failed")
]

# Generate the HTML report
html_report = generate_html_report(test_results)

# Print the HTML report
println(html_report)

Option 2: Using the Mustache package

Another way to generate an HTML report of test results in Julia is by using the Mustache package. This package allows you to use templates to generate HTML code. To use this package, you can start by installing it using the following command:

“`julia
using Pkg
Pkg.add(“Mustache”)
“`

Once the package is installed, you can use it to generate an HTML report of test results. Here is a sample code that demonstrates how to do this:

using Mustache

function generate_html_report(test_results)
    template = """
    
    
        
    
    
        
Test Results
        
Total tests: {{total_tests}}
        {{#test_results}}
            
Test: {{name}}
            {{#failed}}
                
Status: Failed
                
Error message: {{message}}
            {{/failed}}
            {{^failed}}
                
Status: Passed
            {{/failed}}
        {{/test_results}}
    
    
    """

    # Prepare the data for the template
    data = Dict(
        "total_tests" => length(test_results),
        "test_results" => test_results
    )

    # Render the template
    html_report = render(template, data)

    return html_report
end

# Sample test results
test_results = [
    Dict("name" => "Test 1", "failed" => false),
    Dict("name" => "Test 2", "failed" => true, "message" => "Assertion failed")
]

# Generate the HTML report
html_report = generate_html_report(test_results)

# Print the HTML report
println(html_report)

Option 3: Using the Genie package

The Genie package is a powerful web framework for Julia that can be used to generate HTML reports of test results. To use this package, you can start by installing it using the following command:

“`julia
using Pkg
Pkg.add(“Genie”)
“`

Once the package is installed, you can use it to generate an HTML report of test results. Here is a sample code that demonstrates how to do this:

using Genie

function generate_html_report(test_results)
    layout = """
    
    
        
    
    
        
Test Results
        
Total tests: {{total_tests}}
        {{#test_results}}
            
Test: {{name}}
            {{#failed}}
                
Status: Failed
                
Error message: {{message}}
            {{/failed}}
            {{^failed}}
                
Status: Passed
            {{/failed}}
        {{/test_results}}
    
    
    """

    # Prepare the data for the template
    data = Dict(
        "total_tests" => length(test_results),
        "test_results" => test_results
    )

    # Render the template using Genie
    html_report = render(layout, data)

    return html_report
end

# Sample test results
test_results = [
    Dict("name" => "Test 1", "failed" => false),
    Dict("name" => "Test 2", "failed" => true, "message" => "Assertion failed")
]

# Generate the HTML report
html_report = generate_html_report(test_results)

# Print the HTML report
println(html_report)

In conclusion, all three options provide a way to generate an HTML report of test results in Julia. The choice between them depends on your specific requirements and preferences. If you prefer a lightweight solution, Option 1 using the HTMLBuilder package may be the best choice. If you prefer using templates, Option 2 using the Mustache package is a good option. Finally, if you are already using the Genie package or need more advanced web functionality, Option 3 using the Genie package may be the most suitable.
