A fluent assertion library for testing document content in JUnit test cases, designed for structured formats like PDF, XML, Word and Excel.

Right now is’s more or less a quick hack, for basic usage see the JUnit test files.

1. Features

• Fluent assertions on binary document content (byte arrays, input streams)

• Supported formats:

  • Text

    • CSV

    • JSON

    • XML

  • Word (DOCX)

  • Excel (XLSX)

  • PDF

  • Images

    • PNG

    • JPEG

    • GIF

  • ZIP

2. Example Usage

assertDoc(pdfBytes)
    .asPDF()
    .hasText("Bill")
    .hasPageCount(1);

assertDoc(imageBytes)
    .asJpeg()
    .hasImageSize(100, 100);
    .hasCaption("Testimage")
    .hasAverageRgbDeltaLessThan(image2Bytes, 3.0);

assertDoc(xmlBytes)
    .asXml()
    .hasXPath("//total", "100.00")
    .hasRootElement("invoice");

assertDoc(jsonBytes)
    .asJSON()
    .hasValue("$.user.id", "42");
