OK, cool.

The code snippet that appears in your opening post, is that literally copy and pasted? As there is currently a syntax issue with it if that is the case?

I updated it earlier as I noticed an issue. I'm not sure whether you're seeing the revised version so this is the code:

Code:

add_action( 'woocommerce_before_main_content', 'remove_test_category_thumbnails', 10 );

function remove_test_category_thumbnails() {
    if (is_product_category('test-category')) {
        remove_action('woocommerce_before_shop_loop_item_title' , 'woocommerce_template_loop_product_thumbnail' , 10);
    }
}

add_action( 'woocommerce_before_shop_loop_item_title', 'add_test_category_thumbnails', 10 );

function add_test_category_thumbnails() {
    global $post;
    $testCatThumb = get_post_meta( $post->ID, 'step_dad_mug', true);
    if (is_product_category('test-category') && (isset($testCatThumb)) ) {
        echo wp_get_attachment_image( $testCatThumb );
    }
    else
        echo woocommerce_get_product_thumbnail();
    }
}

The following function expects a post id. is that what you are passing it?

Code:

wp_get_attachment_image();

as part of your if condition, you could check:

Code:

is_numeric($testCatThumb);

I tend to create readable variables, rather than having horrible conditions you have to parse with your brain every time you read it:

Code:

function add_test_category_thumbnails() {
    global $post;

    $testCatThumb = get_post_meta( $post->ID, 'step_dad_mug', true);
    $isPostId = !empty($testCatThumb) && is_numeric($testCatThumb);
    $isValidAttachmentId = is_product_category('test-category') && $isPostId;

    $image = $isValidAttachmentId ? wp_get_attachment_image($testCatThumb) : '';

    echo !empty($image) ? $image : woocommerce_get_product_thumbnail();
}
