## Introduction

Some information about your application. 

Any tests that fail show the error in the sections below. The lack of an error message indicates that the test passed. 

## Test 1: The sample mean

This test shows that the mean is calculated appropriately when there are no missing data:

```{r sample-mean-test, error = TRUE}
test_1_inputs <- 1:5
test_1_output <- mean(1:5)
expect_equal(test_1_output, 3)
```


## Session Information

These tests used the following R packages, their version, and source:

```{r versions, echo = FALSE}
sessioninfo::session_info()
```
