give me a CODE example to define arguments when running pytest

Sure, here is an example:
```
def test_calculation():
x = 5
y = 10
assert add(x, y) == 15
def add(x, y):
return x + y
```
In this example, we define a test function `test_calculation()` that tests the `add()` function. We pass two arguments `x` and `y` to the `add()` function and expect the result to be 15. The `assert` statement verifies that the result of the `add()` function is, in fact, 15. When running `pytest`, we would define the arguments for `x` and `y` like this:
```
pytest test_example.py --x=5 --y=10
```
This would run the `test_calculation()` function with the arguments `x=5` and `y=10`.

give me a example to define arguments when running pytest
Sure! When running pytest, arguments can be used to modify the behavior of the test execution. For example, you can use the "-k" argument followed by a string to select only tests whose names contain that string. So, if you have a test function named "test_addition" and you run "pytest -k addition", only that test will be executed. Another example is using the "-s" argument to disable capturing of stdout/stderr. This can be useful when debugging and you want to see print statements. So, you can run "pytest -s" to enable stdout/stderr capturing.
give me a sample code to use psram
As an AI language model, I don't have access to physical devices or hardware. However, here's an example code to use PSRAM in an ESP32 board:
```
#include <Arduino.h>
#include <esp_heap_caps.h>
// Define the size of the PSRAM to be used
#define PSRAM_SIZE 32768
void setup() {
// Initialize the PSRAM
if (heap_caps_malloc(PSRAM_SIZE, MALLOC_CAP_SPIRAM)) {
Serial.println("PSRAM initialized successfully!");
} else {
Serial.println("PSRAM initialization failed!");
}
}
void loop() {
// Access the PSRAM as needed
}
```
This code initializes the PSRAM in an ESP32 board by allocating a specified amount of memory using the `heap_caps_malloc()` function. The `MALLOC_CAP_SPIRAM` flag is used to indicate that the memory should be allocated in the PSRAM instead of the internal RAM.
Once the PSRAM is initialized, it can be accessed as needed in the `loop()` function. Note that the PSRAM can be accessed using standard memory access functions such as `malloc()` and `free()`.
