getFund单元测试金额不对

[dawn21810]

我的本地运行getFund函数测试时，时不时提示金额不对，按照金额推断应该是上个场景测试影响到了，但是找不到原因，有谁知道大概是哪方面的问题
` it("window close,target not reached, getFund faild",
async function () {
await fundMe.fund({ value: ethers.parseEther("0.1") })
//make sure the window is closed
await helpers.time.increase(200)
await helpers.mine()
await expect(fundMe.getFund())
.to.be.revertedWith("target not reached")
}
)

//提示金额不对
it("window close,target reached, getFund success",
async function () {
await fundMe.fund({ value: ethers.parseEther("1") })
//make sure the window is closed
await helpers.time.increase(200)
await helpers.mine()
await expect(fundMe.getFund())
.to.emit(fundMe, "FundWithdrawByOwner")
.withArgs(ethers.parseEther("1"))
}
)`
