Question

尝试实现从其他程序包中调用Java类以提高测试脚本的效率。现在我在每个类上重写login.java之前，都尝试调用它来提高效率，现在发生的是，它可以正确登录但没有跟进。

尝试分离login.java

library(lubridate)

df %>%
  mutate(START = dmy(START), 
         START = if_else(month(START) >= 10, START + years(1), START),
         year = year(START)) %>%
  dplyr::count(Customer, year) %>%
  group_by(Customer) %>%
  mutate(ret = n()/n_distinct(.$year))  %>%
  tidyr::spread(year, n, fill = 0)

Test2.java

df <- structure(list(ID = 1:5, Customer = structure(c(3L, 1L, 2L, 3L, 
1L), .Label = c("Apple", "H&M", "Tesco"), class = "factor"), 
START = structure(c(1L, 5L, 4L, 2L, 3L), .Label = c("01-01-2000", 
"01-01-2001", "01-01-2003", "01-02-2002", "05-11-2001"), class = "factor"), 
END = structure(c(3L, 1L, 2L, 4L, 5L), .Label = c("06-02-2002", 
"08-05-2002", "31-12-2000", "31-12-2001", "31-12-2004"), class = "factor")), 
class = "data.frame", row.names = c(NA, -5L))

应该正常工作，没有错误

由于调用类而导致null异常
