Example:

```sh

// The name must be a relative path: it must not start with a drive
// letter (e.g. C:) or leading slash, and only forward slashes are
// allowed. To create a directory instead of a file, add a trailing
// slash to the name. Duplicate names will not overwrite previous entries
// and are appended to the zip file.
// The file's contents must be written to the [io.Writer] before the next

Activating a virtual environment also changes a couple of other things, but this is one of the most important things it does.

## Checking a Virtual Environment { #checking-a-virtual-environment }

When you check if a virtual environment is active, for example with:

//// tab | Linux, macOS, Windows Bash

            .withSetUp(parentBuilder.getSetUp())
            .withTearDown(parentBuilder.getTearDown())
            .createTestSuite());
    /*
     * TODO(cpovirk): the Map tests duplicate most of this effort by using a
     * CollectionTestSuiteBuilder on values(). It would be nice to avoid that
     */
    derived.add(
        SetTestSuiteBuilder.using(

            } else {

                /* On NT without Unicode the fileNameLength
                 * includes the '\0' whereas on win98 it doesn't. I
                 * guess most clients only support non-unicode so
                 * they don't run into this.
                 */

                /* UPDATE: Maybe not! Could this be a Unicode alignment issue. I hope

   * #expectContents(Object[]) expectContents(E...)} and other convenience methods. The creation of
   * multiple containers in a single method is discouraged in most cases, but it is vital to the
   * iterator tests.
   *
   * @return the new container instance
   * @param newValue the new container instance
   */
  @CanIgnoreReturnValue
  protected C resetContainer(C newValue) {

   * other words, no character encoding is performed; the low byte and high byte of each {@code
   * char} are hashed directly (in that order). The input must not be updated while this method is
   * in progress.
   *
   * <p><b>Warning:</b> This method will produce different output than most other languages do when

This tutorial shows you how to use **FastAPI** with most of its features, step by step.

Each section gradually builds on the previous ones, but it's structured to separate topics, so that you can go directly to any specific one to solve your specific API needs.

It is also built to work as a future reference so you can come back and see exactly what you need.
