NBomber.FSharp.Http 0.0.5

NBomber.FSharp

F# Computation Expressions for NBomber API

Package	Description	Status
NBomber.FSharp	CE for test runners, scenarios and steps
NBomber.FSharp.Http	CE for http calls steps, similar to NBomber.Plugins.Http
NBomber.FSharp.Hopac	Hopac support for the above, depends on both

Scenario

Step

The overloads of step's custom operation execute accepts a function taking a step context and returning either Response or unit directly or wrapped in a task, async or even in a Hopac job <table> <tbody> <thead><tr><th>Fluent API</th><th>Computation Expression</th></tr></thead> <tr><td>

Client factory

Simplified construction of clients. Notable differences are:

• connect and disconnect functions are more tolerant for missing type signatures and arguments
• no need for cancellationToken argument if it is not used in connect or disconnect functions
• disconnect can be omitted completely, if the type of created connection implements IDisposable or can be just disposed.
• count of connections can be omitted too, it defaults to 1
• even less verbose compared to the C# API

<table> <tbody> <thead><tr><th>Fluent API</th><th>Computation Expression</th></tr></thead> <tr><td>

let clientFactory =
    ClientFactory.create(
        name = "db connections",
        initClient = (fun i ctx -> task {
            let c = new NpgsqlConnection(connectionString)
            do! c.OpenAsync(ctx.CancellationToken)
            return c
        }),
        disposeClient = (fun (c:NpgsqlConnection, ctx) -> c.CloseAsync(ctx.CancellationToken)),
        clientCount = 100)

</td><td>

let clientFactory =
    clients "db connections" {
        count 100
        connect(fun i ctx -> task {
            let c = new NpgsqlConnection(connectionString)
            do! c.OpenAsync(ctx.CancellationToken)
            return c
        })
        disconnect(fun c ctx -> c.CloseAsync(ctx.CancellationToken))
    }

Reporter

Imagine you need just a html report. Then it is as short as

report { html }

<table> <tbody> <thead><tr><th>Fluent API</th><th>Computation Expression</th></tr></thead> <tr><td>

    NBomberRunner.withReportFormats [
        ReportFormat.Csv
        ReportFormat.Txt

        [ influxdbSink
          customFormatSink ]

    |> NBomberRunner.withReportFolder "reportsFolder"
    |> NBomberRunner.withReportFileName "reportFile"
    // or if none
    |> NBomberRunner.withoutReports
    ...

</td><td>

    testSuite "Suite name" {
        report {
            csv
            text
            markdown
            html
            sink influxdbSink
            sink customFormatSink
            interval (seconds 10)
            folderName "reportsFolder"
            fileName "reportFile"
